Adds more tests for using SetArgumentPointee with protobufs; works around a compiler bug on Symbian that gmock-printers.h triggers; reduces template code bloat in gmock-matchers.h; avoids RTTI when it's disabled.

Partially implemented SafeMatcherCast (by Vlad Losev); updated the implementation of Not, AnyOf, and AllOf to use SafeMatcherCast (by Vlad Losev); implemented ACTION_TEMPLATE (by Zhanyong Wan); worked around bugs on Symbian (by Zhanyong Wan).

- updates the doc string.
- adds a version number.

0 ClassNames means emit all classes found in the file.

The modifiers (things like const, volatile, etc) were not being added
