Move directory, and Rename "mastodon".

* Redesign account grid cards

* Fix style issues

* Adjust tag and accounts page

* Remove units from 0px paddings

Avatars now have consistent styling across all pages; border radius can be adjusted with a SASS variable ($ui-avatar-border-size)

Fix #2221 - Catch OpenSSL exceptions when loading remote avatars/headers/attachments
Don't strip "rel" attribute from <a> tags when sanitizing (microformats)

- Updates scss variables file to use better-named variables for black/white/etc
- Arranges the "mastodon classic" colors into variables
- Remove all references to `$color-*` naming, replacing with new

This does not in itself introduce "theme" support, but:

- It would probably be easier to start working on theme support after this
  change and others
- Even without the goal of themes, these changes make it more clear how the
  colors are being used.

There is almost definitely some edge case in here where I've guessed the
intent/context of some color usage incorrectly, but it still seems like a net
improvement.
