fixed a few potential NULL-pointer derefs in ValueObject
we have a way to provide docstrings for properties we add to the SWIG layer - a few of these properties have a docstring already, more will come in future commits
added a new bunch of properties to SBData to make it more natural and Python-like to access the data they contain

(b) fixes and improvements to the formatters for NSDate and NSString
(c) adding an introspection formatter for NSCountedSet
(d) making the Objective-C formatters test cases pass on both 64 and 32 bit
    one of the test cases is marked as expected failure on i386 - support needs to be added to the LLDB core for it to pass

1) solving a bug where, after Jim's fixes to stack frames, synthetic children were not recalculated when necessary, causing them to get out of sync with live data
2) providing an updated list of tagged pointers values for the objc_runtime module - hopefully this one is final
3) changing ValueObject::DumpValueObject to use an Options class instead of providing a bulky list of parameters to pass around
   this change had been laid out previously, but some clients of DumpValueObject() were still using the old prototype and some arguments
   were treated in a special way and passed in directly instead of through the Options class
4) providing new GetSummaryAsCString() and GetValueAsCString() calls in ValueObject that are passed a formatter object and a destination string
   and fill the string by formatting themselves using the formatter argument instead of the default for the current ValueObject
5) removing the option to have formats and summaries stick to a variable for the current stoppoint
   after some debate, we are going with non-sticky: if you say frame variable --format hex foo, the hex format will only be applied to the current command execution and not stick when redisplaying foo
   the other option would be full stickiness, which means that foo would be formatted as hex for its whole lifetime
   we are open to suggestions on what feels "natural" in this regard

 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

The formatter for NSString is an improved version of the one previously shipped as an example, the others are new in design and implementation.
A more robust and OO-compliant Objective-C runtime wrapper is provided for runtime versions 1 and 2 on 32 and 64 bit.
The formatters are contained in a category named "AppKit", which is not enabled at startup.

This commit provides a new default summary for Objective-C boolean variables, which shows YES or NO instead of the character value. A new category named objc is added to contain this summary provider. Any future Objective-C related formatters would probably fit here

Short option for --summary-string in 'type summary add' is now -s. This might be a breaking change for those who have summaries defined.

make the C++stdlib string summary work even if for some reason std::basic_string<char> ends up in the debug info instead of std::string

Don't delete & remake the exception breakpoints every time you need them.  Make them once & enable/disable
them as appropriate.
Also reformatted the lldb summaries to make them easier to read, and added one.  I'll do more as I get time.

essentials contains two small summaries that you might really want to use; lldb contains some basic summaries for use in debugging LLDB itself. to use them, you must type category enable lldb
