Error Handling

[thevinchi]

I need to refactor the treatment of error handling across the Kroll bridge. This mostly refers to syntactic errors, where the developer has passed invalid arguments, etc. Currently the Obj-C library is doing empty return; statements with most methods returning void vs. allowing for a return across the Kroll bridge that could indicate a syntactic error, etc.

Also need to look at the JavaScript side to throw new Error() versus return false; in a number of areas.
