Add new user-settings component/route, add options to change name, bio, avatar, banner and bg. Add those options to api service and backend interactor service.

Fix long names overflowing and messing everything (now just overflowing parts not drawn), fix non-square avatars not drawn as squares.

Align attachments with usercard, make buttons use theme colors, prettify login form, more border radii adjustment for consistency.

Make gradient use the theme colors, adjust user interction elements, make profiles without bg use a darker gray solid color to not drown out white text.

Move profile picture to right side, make the names appear next to it, extend profile background pic further and fade it out with gradients, fix the crappy borders around the inline user card.

Changed following-info to user-interactions and moved muting there, made everything in user-interactions look a bit neater

Solarized-dark for now.
