Conditions are moved under functions
Conditions are moved under functions which makes easier to share them as they are also stored like math functions as individual files.
All conditions previously that were defined in config\settings.ini are converted to individual bmscnd files.
WinDarab converts (one-time) the conditions stored in settings.ini to condition files (*.bmscnd) and saves those files in the current math channel base folder. Then the condition definitions are removed from setting.ini.
If users use several different math channel set (-> changing the base folders), then they have to copy the new *.bmscnd files to the other math channel base folders.
