o Initial work on resumeSlice and yieldSlice in callback runtime only (for now).
o IDE was using spaces instead of tabs.
o Changed resumeSlice/yieldSlice event names to the better enter/exit names, as suggested by Bruno.
o 'enter' event can now be used to track entering and exiting whole functions.
o 'enter'/'exit' events no longer fire for simple trampoline pushes.
o Fixed bug with 'exit' event not always firing.
o 'enter' event now passes in the function body about to be executed when entering a function.
o Reverted changes to 'enter' and 'exit' events as they ended up being unnecessary.
o Those pesky spaces made a comeback.
Merge pull request #215 from anodos/sliceEvents
