[FIX] ... not a fix. This circumvents the boos::program_options linker issue when specifying the OW_BOOST_PROGRAM_OPTIONS_FIX flag. Use CMake to inject the flag:  cmake -DOW_CXX_FLAGS_INJECT="-DOW_BOOST_PROGRAM_OPTIONS_FIX".

[CHANGE] Lines having the "boost::shared_ptr< foo > bar = boost::shared_ptr< foo >" idiom have changed to " boost::shared_ptr< foo > bar(..)" in core as well.

[ADD] - added generic structured text file parser in boost::spirit and a first skeleton of a module meta data object. This will later contain many module related info (help, contact infos, webiste URL and similar)

[CHANGE] - openwalnut now has useful --version and --help output. Logger is started AFTER command line parsing. The help output is somewhat standard-conform now. Tools like help2man can create manpages out of this

[ADD #501] added file-log. This prints all log messages to a file openwalnut.log in current working directory.

[CHANGE] - some improvements to the version stuff. This could have been very easy if SET_SOURCE_FILES_PROPERIES would work properly in cmake. But it doesn't. So we need (again) an external, generated version header. But this time: it will work if mercurial is not installed.

[CHANGE] - streamlined logger. Removed a lot of unused methods/members. Restructured. Now one can add MULTIPLE output streams for logs. This way, we can have file logging, console logging, GUI logging and so on using an UNIFORM interface.

[ADD] - added base functionality to logger for notifying others on incomming logs. This will be used by robert in his branch to develop a GUI based notification for error-logs.

[CHANGE] - version information now gets written to header and included during build, this makes revision text file obsolete as well as the walnut script.
