patch

I improved the API between the inspector and JSC. We no longer send one huge
string to the inspector. We now send structured data that represents the type
information that JSC has collected. I've also created a beginning implementation 
of a type lattice that allows us to resolve a display name for a type that
consists of a single word.

I created a data structure that knows which functions have executed. This
solves the bug where types inside an un-executed function will resolve
to the type of the enclosing expression of that function. This data
structure may also be useful later if the inspector chooses to create a UI
around showing which functions have executed.
