[rox-devel] [Archive] Support for upper case extensions.

[Denis M. <de...@li...>]

Changing this way the get_format function of Archive.py should handle
files with uppercase extensions :

from string import lower

def get_format(path, formats):
for f in formats:
	ext = f[0]
	if ext == path[-len(ext):] or ext == lower(path[-len(ext):]):
		return f
return None
