Logged in user text links to their profile page (fix #642)

[dgattey]

Click the username at top left to link to their profile page per #642. Doesn't show reposts, but ordinary profiles don't show reposts, so loading reposts should be a separate issue IMO. A few changes came together for this:

1. Slight tweaking of css of logged in user to make it clearer
2. $state.go to $rootscope.userId's profile from there
3. On profile page, not showing follow button if user is the logged in user (since following/unfollowing yourself makes no sense)

Just commenting to see what you think @weblancaster. Anything else to do before a merge?

[weblancaster]

hey @dgattey my apologies with my super delay in testing this PR.

I was going to merge but before I tested and turns out there is a minor issue.. the reason is that you need to add a null check on the profileCtrl where we call replace.

I'm merging and then fix myself so we don't prolong.
