Fix Issue #3511

when inserting a hint which is not a valid property name, such as 'my-key', insert the hint as ["my-key"] instead of .my-key.

insertHint now runs the hint through the acorn tokenizer to see if it looks like a valid property name.  If it's invalid, it replaces the '.' with brackets.
Refactored some code in Session.getType() - pulled out a method to find the leading '.' in a property lookup, and use that method from the insertHint logic as well.
Added 3 new unittests to test this new behavior.
Better error messages for AddMenu and AddMenuItem
Update tern - fixes #3606, #3605

Also update acorn, as latest tern needs the latest version of acorn.

Codehinting tests all pass, and performance does not seem to have degraded.
