Make control + enter submit forms if a textarea is focused

Summary:
This is straightforward, except that `form.submit()` does not call onsubmit handlers. Create a `didSyntheticSubmit` event and have everything which listens for form submits listen for it too.

Fixes T704.

Test Plan: Hit control + enter in inline comments, main commetns, Pholio, conpherence. Verified it triggered appropriate JS (workflow / special behaviors).

Allows a button type for menus, used in Conpherence

Summary: This adds a new menu item, TYPEBUTTON, for use in Conpherence and maybe others over time. Note I need to add icon support, but I'll make them later tonight. I also changed the front facing names to 'Conversations' which is way more natural. Basically, Pholio has Mocks, Differential has Diffs, Conpherence has Conversations.

Test Plan: Tested Conpherence on mobile and desktop.
