Removed necessity of zsh/regex by using `cut`
A cache file is used for completing installed libs

I hope I can simplify this later
Another cachefile for remote libs
Added possibility to invalidate the haxelib completion cache
Using _wanted again for `haxelib install` completion

This ommits the descriptions but solves the problem with consolidated
entries.

FIX #4 `haxelib install` completion is putting items together, that
doesn't belong to each other
First step for completing `haxelib set`

Next step would be to complete the available versions
Dispatch structure and `haxelib update`
Just display a message if not completable
Simple `haxelib install` completion
No need for completing `haxelib upgrade`
Spit out a message on not implemented completions
Cleaned away old code in comments
haxelib install completed without description for now

FIX #4 `haxelib install` completion is putting items together, that
doesn't belong to each other
haxelib install might possibly complete

I have to check when I have internet access in the late afternoon.
Moved uncompletable subcommands to a case in dispatcher
Remove does complete now!
Merge branch 'feature/rewriteToDispatch' into develop
Quick completion stub for haxe

But seems to work quite well so far... I should have begun with this one,
not with haxelib...
