Allow the script cleaner to change all longform into shortform automatically

ability = use
endif = ei

and so on to eliminate all long form ways of writing and still keep all "old" scripts compatible with the single simplified uniform way of writing scripts

This might be able to built into the beautifier

I think it would've been better if the original author never added both commands because I don't think it would be a good idea to remove ability now with all the existing scripts using it. But replacing it with use with the beautifier looks like a good idea to train people :-p

And personally I don't like the suggested ei beautifying (didn't even know this is a thing, but looking into snippets.lua I also see self/enemy/ally and never knew of ally ;-) ). if/endif feels better for understandability/readability of scripts :-)

This wouldnt convert into short form - but rather the preferred form. ability, endif, self are all the preferred form. We can deprecate the other functions by posting a warning message in the chat and eventually removing them from the language.
