Clean up repository - removed unwanted files:
Removed .class files
Removed /target folders
Added output folders to .gitignore
Clean up build path:
Removed xtend-gen source folder for projects which do not contain Xtend
sources
Removed usage of internal type BundleURLConnection
Used FileLocator instead to locate the File for a bundle entry
Avoid a ValueConverterException:
Overridden method assertTokens to detect an ambiguity between the NAME
and ID rule. Ignoring this case.
Fixed quick fix addModelGlobalAlias by replacing the semantic
modification by a document modification
