saving user config. changes
New feature request: - to be able to save user changes to configuration xml files.
- specify directory or file to contain user changes
- add a "user_save" method to config object
- path for value to change
- new value
- saving happens in the global user changes file (see 1)
- format can be "xml file path | path to value | value"
- when loading a xml file, cool has to check for modified user values in the user changes file and to update the xml tree in memory
