Issue 3 Fix

[JayWood]

Fixes #3 and is really nice to have :)

Changes

• Add extra dialog structure to allow users to create snippets in-post, fixes #3
• Fix rogue text-domain
• Reset form after closing it

If you can fix the TODOs, I'll tweak a bit and merge this in. Looks great! If you can add the WP spinner gif during the snippet creating, bonus points.

Works for me, was going to work on that tomorrow anyhow. As for the debug, must've slipped past me. I'm used to jshint complaining haha.

@jtsternberg I've merged this branch into mine, based on your latest master-branch: https://github.com/marbetschar/Code-Snippets-CPT/tree/feature-postsnippet

This pull request looks good to me - despite the fact, the buttons are too close aligned on top:

But this can easily be adjustet by using the following code:

#snippet-cpt-form { padding:10px 10px 20px }
