commit 047dee5a3b934a115db0d5497eda4cbf4865400d

Basic support for \babelprovide
This is the new(er) babel mechanism to load languages via babel *.ini
files.
Some languages (or varieties) are only supported this way, some work
better with unicode engines this way (for the latter case, we have
BabelProvide 2)
