Add a makepot script.

Mainly for gnome-wall-clock.c time formats. The inherited
translation msgids still match up, but if we have to change
anything they'll need to be re-done.

These changes result in there being too much space between some
elements in certain cases (like single digit date):

We may want to adjust these standard formats to use %-e instead
of %e, etc...
