Update form styles, implement in many places

Summary:
This creates a common form look and feel across the site. I spent a bit of time working out a number of kinks in our various renderings. Some things:

- Font Styles are correctly applied for form elements now.
- Everything lines up!
- Selects are larger, easier to read, interact.
- Inputs have been squared.
- Consistant CSS applied glow (try it!)
- Improved Mobile Responsiveness
- CSS applied to all form elements, not just Aphront
- Many other minor tweaks.

I tried to hit as many high profile forms as possible in an effort to increase consistency. Stopped for now and will follow up after this lands. I know Evan is not a super fan of the glow, but after working with it for a week, it's way cleaner and responsive than the OS controls. Give it a try.

Test Plan: Tested many applications, forms, mobile and tablet.
