Some path adjustments for windows (untested) and fonts. All types of option can be edited. paths: support for getting the full path for a font when just the file name is entered, in order to unify usage on windows and linux. paths: Used getSpecialPath for some windows paths; needs testing. Content: Moved line-editing code to abstract ValueContent class and added some conversion functions, so that any type of ValueContent can be edited as text.
