WIP: array test fixes
Moved some of test for #640 to SDK following arrays changes
Updated some tests due to language module changes
CeylonDoc: only add output modules to the classpath coming from the output repo

Otherwise we get stuff coming from the cache or who knows where and it's just not
relevant at all
CachedTOCJars: added toString()
Fixed CeylonDoc test for SDK

removed the -native repo and merged it into a single repo, added new array java types
Fixed test for removal of Cloneable
