[patch] build and install translations (and manpage)

[Benjamin Pineau]

Hi,

The attached patch modifiy the Makefiles to build (from sources .po to
binaries .mo, with msgfmt) and installs (in
/usr/share/locale/*/LC_MESSAGES/powerpot.mo) the translations files in po/. 
It also gzip and install the manpage.

Notes :
- The patch create a new po/Makefile file, so it must be applied with "patch
  -p0" (without "-p0" everything ends up in main ./Makefile), and be svn added.
- The install path LOCALESDIR is an overridable make variable, but for now only
  the default path will work (/usr/share/locale/ is hardcoded in powertop.c).
