*	updatepo cmake rule	Giuseppe Bilotta	2011-07-22
| | | | | | | | | |	Get rid of the system-specific updatelocales.sh and introduce an updatepo cmake rule. po files are also updated before creating the mo files, and we now keep the .pot file (in the po/en directory). To stabilize the po file creation, file contents are sorted by source filename. Update po files in the process.
*	Static naming of po file	Giuseppe Bilotta	2011-07-22
	The po file should not be named c55 if we're in ∆. But since it is not exposed at installation time, we don't actually need its name to be based on the project name at all, so just call it minetest.po
