I removed AST.mli from CameLIGO (for maintenance's sake).
I removed useless functions.
I renamed unlexer.ml to Unlexer.ml
I added a cleaning rule for my Makefile in Makefile.cfg
I also had to remove the keywords [Down], [Fail] and [Step] in
PascaLIGO that made a mysterious and unwanted come back. (I did not
bother with [git blame]).
