Fix #261: Class members added in code are shown twice and some more problems with overloaded methods.
Removed unneeded "+" signs in front of assembly reference tree nodes.
HACK: eagerly load output pad because pad services cannnot be instanciated from background threads.

A proper fix would be to separate the IOutputPad implementation from the UI, so that output categories can be created and written to from background threads without waiting for the output pad UI to be created.
Don't show CS1729 error message if base type is unknown.
Fix #227: Class no longer available for code completion when file renamed
fix #267
fix #266
only use fully qualified names for type and member definitions
