make it run on windows (msys2/mingw64)

[carlos22]

Some modifications to make it work on msys2 (tested with mingw64, should work with mingw32).
Some discussion about a windows version: see issue #11

Known Problems / TODOs

• fix translations (only english currently)
• fix delete of temp files on exit (there is some code in the old win version)
• fix about dialog (argv0 is python3w in some cases)

@carlos22 I was not able to reproduce the error you talk about in 8286d17

Could you confirm that

Closing. Only localization remains so the story will continue at in #19
