Feat: when ng-click is fired suggest similar functions if no bound is found

[btford]

This should generalize to all ngEventDirs, e.g. ng-focus, ng-mousedown, etc.

@caguillen214 and I are pairing on this issue.

• We have found that decorating the compilation of the event directive functions allows us to check if the function exists on the scope.
• We need to check our logic to make sure it works with expressions
• We need to check our logic so it works with the regex for checking functions with parameters
• We need to suggest similar functions.

@btford: our current logic would console.log a message when the directive is instantiated rather than when the event function is fired. Is this acceptable, or do we want it to specifically fire when the incorrect function is accessed?

This module for Angular Hint has been mostly completed at https://github.com/caguillen214/hint-event, we're still working on the tests though.
