CMS-700 Improve loader

* The splash-loader appearing when updating lists etc looks bad, should only display a pure white background + animation.
* Also, there should be a splash loader when loading a brand new app

CMS-819 Updated ContentDao to store version history
CMS-800 UI: Facet text search box: Replace trigger with background image

- Remove the trigger
- Keep magnifier glass

See the "search email" text field here:

For all apps, the details panel and list panels in the browse view should by default be 50/50 in size. Currently the details panel is too small.
