Remove usages of ScalaCodeScanner.tokenize(d:Idocument, ...)
Removed ScalaTemplateParser dependencies on scala-ide, ScalaTempalateCompiler

ScalaTemplateParser depended on:
* The TemplateTree classes in ScalaTempalteCompiler ==> These have been refactored to a separate file.
* HasLogger ==> Logging has simply been removed

These changes are in preparation for when ScalaTemplateParser is split off into it's own project.
