Update

* Fix borders and width on profile header (in profile page and modal)
* Fix stats padding in dashboard
* Bring in tons of theme overrides for link color, then reset more links to override those
* Move the timestamp back to the right, and hide it's generated content dot
* Add transitions to nav links and new tweet bar
* Restyle topbar nav links to be lighter by default, and white for active and hover
* Unfuck some of the super inconsistent topbar right nav actions (DM, settings, new tweet button)
* Remove the now unnecessary horizontal padding on `.wrapper`s because there is no more background wash
* Makes gutters between dashboard modules, dashboard and main content, and navbar and content below more consistent (now all at 14px, edge to edge)
* Make DM count match navbar background color
* Prevent accent color on new Tweet form background color (need to still do the buttons)
* Added button styles, but commented them out for now because they're kinda whack
* Improve nav links in the dashboard
