Fix possible crash when consuming Android string files.

Twine would crash if --tags were supplied on the command line. This
parameter is undocumented for consume-string-file. It shouldn't do
anything (at least not yet).

Fixes #23
Fix bug in generation of .po comments

It was written ".#" but should have been "#." for extracted comments
Fix regex for reading gettext to be more lenient and remove extra logging

We don't distinguish between the types of comments and should allow space between
the field type and the value.

Also, the extra logging was accidentally left in and should be removed
