use the python API that is exposed through SWIG to do some cool stuff.

Also fixed synchronous debugging so that all process control APIs exposed
through the python API will now wait for the process to stop if you set
the async mode to false (see disasm.py).

order to customize the running of the test suite.  For the time being, the
supported customizations are:

o redirecting stdout and/or stderr
o specifying a list of compilers to build the test programs
o specifying a list of architectures to build the test programs for

Also checked into the examples/test directory some example files which
demonstrate the usage for the above customizations.

up a seciton offset address (SBAddress) within a module that returns a
symbol context (SBSymbolContext). Also added a SBSymbolContextList in 
preparation for adding find/lookup APIs that can return multiple results.

Added a lookup example code that shows how to do address lookups.
