Model loader #1411: make sure packages are unquoted where required
AbstractTransformer #1411: make sure we look up java.lang.String in the jdk module
CeylonEnter #1411: load the package list when adding the module to the classpath like we do in other model loaders

this makes sure we also do it for cyelon modules
LazyModule #1411: better lookup to find if a package is in a module
LazyModuleManager #1411: made an error message deterministic
Test for #1411: Errors can still prevent binary generation for unrelated modules
LazyModuleManager: extracted version sorting to CMR
Updated error messages now that versions are ordered
