Wagn 1.10

Wagn 1.10 introduces some significant interface changes.

Most notable is the new menu, which opens as a dropdown from a gear icon in the upper right corner.  This new menu reduces visual noise considerably and replaces the functionality of the old header, the old footer, and several submenus.  It also helps separate out the "wagneer" functionality (under "advanced") in order to keep things simpler for casual users.

Also cleaned up: forms.  By getting rid of details other than the fields being edited, we were able to make forms far less noisy.  Name and type fields now align vertically with content fields, and old edit submenus are obviated.

As part of the cleanup, CSS is considerably simplified, and behavior on mobile devices is incrementally improved.  Both will receive considerably more attention in upcoming releases as we roll out new support for skins and mobile-friendliness.
