Translations update
A simple window management tool which:
* Allows you to set basic rules for a window type, such as maximise|undecorate
* Allows exceptions to the rules, based on string matching for window name
and window class.
* Allows 'reversing' of rules when the user manually changes something:
* Re-decorates windows on un-maximise.
