Adding New Metronic Theme

Metronic theme currently has 12 different themes and AspNet Zero includes them all. However, you might want to add a new theme option designed by your team to those options. This document explains step by step to add a new theme option to AspNet Zero. Just note that, the added theme must be a Metronic theme or at least it must be compatible with Metronic.

Rest of the document will use ThemeX as the new theme name.
