Remove ui-router, remove modals, store filters in cookie.

Removed ui-router and replaced it with ng-route. Routes only map to main
functionality secions like "my-projects" or "project" or "admin"
etc. Nested views are now handled using ng-switch and ng-include
watching a shared.state variable in the parent controller for each
section.

Modals have been completely removed due to lag and some
incompatibilities with the latest version of angular. Task and project
editing have been moved to a subview within the current parent state.

Filter presets are now stored in a cookie so that every time a user
selects a filter preset, it persists across sessions.
