I tried a very simple approach and just imported gettext into the
buildins.py. It would need to go somewhere central later on.


This is my code:

There are just two translated strings in my testing, and I got the
following result running 50 times "bzr st -h" in a clean branch:

trunk, revision 5813:
real	0m5.933s
user	0m4.880s
sys	0m0.960s

my i18n branch:
real	0m5.981s
user	0m4.896s
sys	0m0.948s

The results vary by maybe .02 seconds, so the performance decrease would
have to be measured again when there is more i18n done.
