Syn doesn't handle typing various shifted characters properly

If I run `syn.type` for "{" or for any capitol letter (A-Z), the event comes back with a `keyCode` of 0 and `undefined` `which` and `charCode`s.

Testing in chrome.

Start by reproducing the issue through the syn.type entry point in Chrome with "{" and capital letters A-Z. Trace how shifted characters are converted into synthetic keyboard events and compare the resulting keyCode, which, and charCode values. Done means these characters produce defined, correct event values.
