Fixes #12 and refs #13 - Refactors both Helper json methods
Fixes #12 and refs #13 - Refactors both Helper json methods

Now H::json assumes that you are doing a 'full json response' and so
doesn't escape anything it doesn't need ot.

H::jsify assumes you are injecting it into your html, and that it needs
to clean things up to be safe.

Note that these will not work, if you are doing more custom JS
injection, where extra "'s that appear might mess you up.
