Open Source release prep - Content manager

This is an interim release, There is a lot of work to complete for v0.99 so I am doing alpha releases until it is ready, there will probably be 3 alpha releases and then v0.99.

• Removed the Template designer, it will return after the Content manager is complete, it will essentially be a minified Content manager
• Content manager is currently being reworked, I've ripped out the old div code, replacing it with a new system to fully support Bootstrap, columns and rows
• Updated site content
• Simplified add and edit for each designer, now have a single form rather than separate add and edit forms
• Major rework of controllers to remove duplication that has developed over time, added action helper to help with this
• Simplified the tool forms in the Content manager, now extend a base classes which does more of the heavy lifting
• Moved Javascript preview functions for Form builder into their own file, will make it simpler to enable and disable the feature
• Tool tabs now either have just glyphs or glyphs and text, depends on the current layout mode
• Updates to the responsive layouts for all designers
• Fixed a bug where sign out is shown on sign in page
• Fixed a bug with move fields tool in Form builder, selector incorrect
• Splitting and updating the Javascript, going back to per designer files
• General fixes, improvements and clean up
• Code style updates
