lots of little changes: - allow revno to be used in most urls where a revid is desired. - clean up the upper right navbar; no more "-300 -100" confusion - the upper left navbar is now always the same, never contextual - for the 3 pages that had contextual buttons in the upper-left navbar, move them to little side-arrows underneath the h1 - add "jump to diff" link next to modified-files in /changes and /revision - add date to inventory-view - add copyright credits from bazaar-webserve
