Restructure the links section in the sidebar to split it into two
major groups, help and community and move the diary link from a tab
to the community section of the sidebar.
Uses the parent of the tabnav element to do its positioning, and fixes
this style in RTL and small.
Also move the greetings block into the top-bar div in order to cleanly
have it share a border with tabs.
Move font sizes and line heights up in the stylesheet structure
to make the left element more uniform. Make the padding of the
menu the same as the other elements.
This is a mild restyling of OpenStreetMap. Changes include:
* Remove margin from map, add more margin to text content
* Rearrange permalink & link buttons and gives them a background
* Pull OpenStreetMap text below logo along with subtitle
* Simplify sidebar styling
* Move towards a baseline, start to consolidate text size and line height
This is tested with LTR, RTL, and the compact mode, and looks good. Looks
more uniform in older browsers because it relies less on round corners.
