modify config_ini.py to take in account the strange behaviour of the configparser module which needs to open (on Windows systems) the file utf-8 files with a call to codecs.open
(helpcharacters.py) fixed a typo relative to the header
(helpcharacters.py) open() uses : encoding='utf-8' (a mandatory trick for Windows systems)
new file : cstate.py
* button apply works
* added a call to DCharsFEError in EditorComboBoxDirection.getValue()
* added CBoxStrings class in order to simplify comboboxes with only a string (the option name) relative to a combobox (options value)
* stuff_to_do_before_exit() is called before exiting the program.
* the splashscreen is more verbose (languages, transliteration methods)
