a) adds a Python summary provider for NSDate
b) changes the initialization for ScriptInterpreter so that we are not passing a bulk of Python-specific function pointers around
c) provides a new ScriptInterpreterObject class that allows for ref-count safe wrapping of scripting objects on the C++ side
d) contains much needed performance improvements:
1) the pointer to the Python function generating a scripted summary is now cached instead of looked up every time
2) redundant memory reads in the Python ObjC runtime wrapper are eliminated
3) summaries now use the m_summary_str in ValueObject to store their data instead of passing around ( == copying) an std::string object
e) contains other minor fixes, such as adding descriptive error messages for some cases of summary generation failure
