Add conditional to admin script loading so that they are only loaded on Titan admin options pages. This fixes a bug that was occuring in WP 4.0 alpha in which the grid view of the media library breaks as a result of `wp_media_enqueue()` being called on this page.
Update admin panel HTML output to more cleanly display.
Merge pull request #136 from MickeyKay/master

Accepted: Fix major conflict with wp_enqueue_media() and media library in WP 4.0
