\class UiGuiIniFileParser
\brief UiGuiIniFileParser is a simple ini file format parser.
These ini files need to have key-value pairs in the style
"key=value". Groups can be defined by writing the groupname
in the style [groupname] before some key-value pairs.
The reason why I use my own class instead of TQSettings is mainly that
TQSettings always internally sorts the groups alphabetically and also
rewrites a settings file sorted. Very annoying for me.
