rejig css:

* sans-serif font
 * use display: table for the message list so that everything lines up nicely
 * switch to flexbox layout rather than position absolutes to avoid assuming a full screen UI and improve maintainability (and better match atomify)
 * neutralise the colouring and styling of highlighted rooms in the recents list
 * switch from ul + li's to a series of divs in some places where the li's are achieving nothing but adding more complexity to the DOM
 * add mx_MessageTileType as a generic css base class for all message tiles
