Adds support for XenForo 1.2 template modifications

Just a simple few lines of code that fetch all Template Modifications (Admin, Public and E-mail), merges them into one array, sets the replace value as template and runs it through the _findPhrasesInTemplates function.

The add-on works absolutely great in XenForo 1.2 and this is the icing on the cake. I would wholeheartedly recommend removing the style customisations from dev_kit.css.

The default XF Admin CP styling has changed somewhat making those custom changes redundant (and I often used to remove them anyway!)

Keep up the great work, guiltar :)
