keyboard control & quill formatting

Hey there. This is the first time I'm writing release notes for TCK and I'll be brief, the main point of this is to set a precedent anyway.

The focus of this update is improving Web Controller post builder mod. Among other things there's:

• Polished keyboard control of the form. You can even focus tag buttons via [Up] / [Down] keys.
• Quill form formatting in the post text field.
• Multiple style fixes.

Have fun, stay focused, do rock. Later.
