Version 1.0.4 (2014/02/19)
--------------------------
 - Fixed issue #43: improved check that determine if polib is dealing with a \ 
filepath or unicode content
 - Fixed issue #44: polib now checks MO files revision number and throws an \ 
error if the number is unexpected

 - Fixed issue #47: added flags attribute for MOEntry to be consistent with POEntry
 - Fixed issue #49: use integers rather than strings for msgstr_plural keys
 - Fixed issue #51: if a PO file ends with a comment, polib adds a spurious \ 
empty entry at the end
 - Fixed issue #52: bad magic number written on big endian platforms
 - Fixed issue #53: added a __hash__() method to POEntry and MOEntry classes
 - Fixed issue #54: use lowercase for state identifiers. This fixes issues with \

doesn't handle very well universal line endings
 - Make sure the mo file is closed at garbage collection, this prevents warnings \ 
on unclosed file when running tests with python >= 3.2
 - Better way to test endianness
 - polib download URL is now on Pypi
