Breckprog-refactor frontend modifications

This is the branch with some modified front-end for the toolbar as a separate app.

Things done.

- Removed 'hide' button
- Removed key-bindings
- Removed close button (For panel contents)
- Minimal HTML for the toolbar panel

Here are just the modifications of the current code. I will work on the new front-end from now on.
Probably with modified bootstrap to reduce the codebase to maintain.
