Reformat the window res logging to "WxH".

The tabstops in the old formatting made for some weird formatting that's
always bugged me, but never enough to fix.

It shall bug me no longer!  :P
Update translations.
Bump Project-Id-Version to "hoverrace 2.0".
Update Report-Msgid-Bugs-To to point to GitHub.

The GitHub issue tracker is currently a much more reliable way to report
bugs, including translation bugs, than the email address.
