general: customization support of Bootstrap core with LESS

Few comments on the setup when you checkout:

$ npm install
$ bower install
$ grunt prod    // copy the libraries and compile LESS to CSS 
(optional) $ grunt dev // when developing on LESS file, a watcher auto compiles on save

The inspire.less includes all the styles that inherits from custom-variables.less where you can specify your own styles without overriding every time the Bootstrap's default styles.

Coming up the polishing of the site using our custom theme! :smile:
