        - Implemented displaying variables for Drosera on Win.

        * Drosera/win/DebuggerDocumentPlatform.cpp: Changed Drosera functions
        that retrieve variables to not hold onto the return value since it's
        not returned.  Also changed to use the new signatures of the retrieval
        functions.
        (DebuggerDocument::getPlatformLocalScopeVariableNamesForCallFrame):
        (DebuggerDocument::platformValueForScopeVariableNamed):
        * Drosera/win/Drosera.cpp: Removed a needless TODO.
