The program may not be installed because it is not needed for non-dev
activities, so it is better to check at the beginning than to let the
compilation fail later. The check is done only if the user has specified
that he wants to install translations.
Took the opportunity to make the generation of "mo" file follow the silent
rules in Makefiles if user enabled them.

The main change is to use Autoconf's syntax for consistency;
Now the detected program is used in the makefiles (user has the possibility
to change the name of the command);
A conditional is used to avoid enabling make targets that would fail if
the command does not exist.
Took opportunity to implement the silent-rules compliance to POT generation
rules.

The code was moved to a dedicated file (wm_i18n.m4) to reduce the size of
configure.ac;
It now searches for gettext+libintl only if LINGUAS is specified, because
there is no need for them otherwise;
The list of supported locales is created automatically from the list of
files present in the source tree, so there won't be problem forgetting to
update the variables when a new language is added, or removed because
one is considered outdated;
The new syntax is now using as much as possible Autoconf's syntax to ensure
consistency and better portability;
Took opportunity to improve the language check loop to make it smaller and
to tell when a locale that the user asked for is not fully supported.
