[misc.js] Added Page Header Border Color support
[typography] Added Headings Small, Text muted, abbr border color support
[Docs] Added Page Header and Headings Small color in theme files
[theme-modifier] Added Two Way Data binding. Fix #4, Close #5.

This now allows inputs to declare a `data-cluckles-{{type}=“property”`
and the data binding will automatically be applied and managed by the
matching {{type}}.js file. Along as that js file has a `modifier` which
matches the `property`.

The DOM Element which has the binding will automatically update the
modifier and apply the change, aswell as be notified when the modifier
is changes (such as when using the API).
[Example] Fixed Typo in Breadcrumbs example
[label.js] Renamed label-base.js to label.js
[Example] Changed Editor templates to use Two way data binding
[Example] Added Button Hover Border Color support
[Example] Added Default Branding/Formstate support
[Example] Removed Pager ActiveColor/Bg from editor. Unused by bootstrap.
[ThemeEditor] Added TWDB to the JS editor files.

Added Two Way Data Binding to the JS files which make up chuckles.
This now means that the data binding that is attached to the editor
HTML templates is now accompanied by changes to the JS so it is now
completely functional.

All that it needs now is to trigger the binding and update the view
when theme files are loaded.
[Variables] Added @brand-default related vars for consistency
[Example] Changed some inputs to numbers, and added placeholders and limits
[Example] Changed BootstrapThemeEditor to Chuckles in Navigation
[Example] Improved download panel information
[ThemeEditor] Lowercases/non pluralised JS files
[Example] Non-pluralised Example/Editor files
[Src] Improved concatenation, stopped window polution

The IIFE which wraps all of the files is now added using concat using
the banner and footer options. The individual src files now don’t add
themselves to window, and they are just used by theme-editor.js.
[ThemeEditor] Changed bsThemeEditor.js to cluckles.js
[Editor] Renamed ThemeEditor to CluckledEditor
