Initial support for interpreting dispatch functions.
Split XtendInterpreter into a standalone and a IDE (aka workspace) version.
Slightly decreased version number for dependency to jdt.launching.
Removed resulting files (e.g., bin) from git, added and adapted gitignore files.
Switched to usage of new WorkspaceXtendInterpreter.
Removed reference to folders which aren't needed.
Set encoding in project to UTF-8 explicitly.

This avoids problems with the template generator, even when the workspace encoding is set differently.
Fixed path to handler class.
