Support for values stored as integral and fractional part
in two following registers. Alpha version.

Removed unit_id logic inherited from mbdmn. In borutadmn each
unit is handled by separate client/server object.

https://newterm.pl/redmine/issues/78 - disabling not defined draw
with Alt+<num> in draw3 caused closing program with error code

* missing linking with boost_locale
* AX_BOOST_BASE called with wrong argument escaping

+ too much code cleanup ('make install' error).

+ a few (un)install commands in resources/Makefile.am did not support
DESTDIR - as a result files were installed/removed directly in/from system.

+ add option draw_name to proxy location configuration
+ add proxy draw_name as a suffix to every location that comes from it
  if its not empty
+ empty draw_name is default so suffix have to be configured
+ update config sample

+ directories listed in <package>.install files are copied recursively,
in this case simplest solution for including empty directory is listing
it in <package>.dirs file.

+ in some cases previous code was sending same line twice becasue all
  data was stored in same buffer
+ now there is one buffer for one line

+ removed unused 'sysinfo' script and cron jobs (from szarp-server
  package).
+ /etc/szarp directory is now created by szarp-base package.
+ updated certificate data for SSS.
+ removed some unused and unpackaged cron file for sss.

+ send 'connect' command before any other so messages order is always valid
+ make write buffer member cause boost asio doesn't copy buffers

+ don't delete objects before they are accessed:/

+ first, check if the provided path is really a svn repo, if not abort without modyfing anything
+ using bash fixes the "unexpected operator" error on debian 7.5

+ check if repo path doesn't end with prefix (avoid ../prefix/prefix paths)
+ ask user if generated paths are correct before proceeding

+ IconvWrapper gets new method isutf8() - a fast way to check whether
the encoding is UTF-8.

+ utf2local(), local2utf() and local2utf_ign() functions reinterpret
cast on UTF-8 system, rather than performing conversion from UTF-8 to
UTF-8.

+ parameter lists (.xpl) are now always saved in UTF-8 encoding.

+ name field in template create/edit window is filtered and allows only
alphanumeric characters.

+ template filenames are transliterated to remove any diacritics.

+ added .gitignore for 'iks-server'.

[enhancement to commit e9c2f8d5]
* user should also be able to search by prefix on a configuration list
  (as they are displayed).

+ functions ascii2utf(), local2szarp() and local2utf() have new variant
(with '_ign' suffix), which omits invalid characters (in the input
encoding) and ignore characters that cannot be represented (in the
target encoding).

+ functions A2U(), L2S(), L2U() get additional argument named
'fallback'. If it's set to "true", in case of conversion failure (due
to invalid multibyte sequence) function catches an exception and tries
to repeat conversion using '_ign' function variant. 'fallback' defaults
to "false", so existing usages will preserve behavior.

+ set 'fallback' to "true" in L2S(), L2U(), A2U() calls, where input
encoding is uncertain.

+ changed A2U() calls to L2U(), where proper.

+ szarp-iks package now setup websocify between ports 9002 and 19002 at
  system startup. Other ports could be specified in
  /etc/default/szarp-iks config file.

+ now iks-server syslog messages would be saved in
  /var/log/szarp/iks.log file

+ in case of invalid probe server connection server was flooding syslog
  with error messages

+ restart command of parstart init script restarts also iks-server
  server if installed. It doesn't start nor stop it.

+ now there is an option to create pid file
+ pid file contains pid of server after daemonizing
+ in case of exception server returns error code

+ add szarp-iks-server package with binary and configuration file
+ add szarp-iks virtual package that pulls iks-server, apache and
  websocify
+ iks-server init script
+ dependencies in parstart init script

+ update configuration sample with comments
+ install sample configuration to /opt/szarp/iks
+ default read config file at /opt/szarp/iks/iks-server.ini

+ mainly remove unused variables
+ split string concatenation -- in c++11 this is mixed with suffixes

+ remove title setting in szbwriter cause its not used anywhere

+ switch from std::cerr to szarp liblog
+ configure liblog to print to syslog
+ add additional log errors in places signed by TODO
+ add error handling in main function -- global try/catch block:)
+ if run not daemonized log is send to stdout

+ server is now going in background as default
+ option --no_daemon is available to disable daemonizing
