Big step forward nodes UI translation:

*Add menu is now translated.
*Nodes' title is now translated.
*Nodes' sockets' labels are now translated.

However, about the last point, and unless I’m mistaking, we’ll have to add the "i18n tag" N_() to all sockets' names, in the input/ouput templates declaration, in all nodes' files, as those sockets are collections created at runtime, I think po-generating script has no way to access that from bpy.types... Quite a piece of (borring) work. :/
