Updated ScalaTemplateCompiler, need help with a compilation test

I updated the ScalaTemplateCompiler from the latest version of Play 2.1.0 and updated the dependencies for Scala 2.10.0. Finally I understood the isByNameParam API change in the new Scala (now I need to ask to the symbol instead of the modifiers of the ValDef).

Major problem is a particular test is broken. The test TemplateCompilationUnitTest is failing because it is using the PresentationCompiler outside the compiler's thread. Then: "Race condition detected: You are running a presentation compiler method outside the PC thread"
