Paste - kill tabs

Summary:
merge paste create and paste list into a single controller.  Add a "filter list"
to the left hand side and have new "create w/ recent", "my" and "all" views.  UI
wrinkle -- "create w/ recent" does not paginate the recent pastes and instead
upsells the user to the new "all" view.

Also includes a business logic clean up or two for simplicity of code.

Test Plan:
- created a paste from the UI
- tried to create a paste with title and no body
- tried to create a paste with no title and no body
- viewed the paste list on "create" view
- viewed the paste list on "author" view
- viewed the paste list on "all" view
- viewed page 2 of the paste list for "author" and "all" views
- "forked" a given paste through completion
