Fixes#4349
* Tweak position of labels to align better with background border.
* Increase z-index of share button to prevent it being obscured by
avatar.
* Move share button to bottom left corner to prevent it obscuring
avatar name.
* Round corners for UI elements / “8-bit” outlines for RPG elements.
* Tag bar – Make it clearer that “Tags” is a heading, not an option
* Task filters – restyle in line with tag bar + nav menu
avatar.jade was applying a class of .notBackground, but the css in
avatar.styl used .noBackgroundImage.
* Changed .notBackground to .noBackgroundImage in avatar.jade and
avatar.styl
* Consolidated css and added more comments
* Amended spacing as Stylus wasn’t compiling correctly
* Removed #profileStable and .pet css as couldn’t find reference to
them anywhere else.
* Commented out styles indicating who is party leader for now. Need a
solution that doesn’t involve background color.
