Console:
- /logs: fixed environment/running info table resize on focus (ticket #1996)
- Scale theme/language divs so we don't truncate language display
- Arabic (light) adjust font size for sidebar elements
- Sidebar network status display (ticket #1996)
- Usability:
  - Enhance presentation of tables on /peers (improve header/column alignment,
    center to separator for multi-value rows)
  - Enhance presentation of tables on /tunnels (reliable alignment of mixed
    content in rows, more prominence to bandwidth tiers)

I2PSnark:
- Usability: add tabindex="0" to screenlog
- Update navbar link classes to allow easier targetting of button type 
- Remove disabled cursor for known tracker radio icons (ticket #1996)
- Fix alignment issue for comments (ticket #1996)
- ubergine: further optimize theme to reduce scroll lag (ticket #1996)
- ubergine/vanilla:
  - Add mini-mode at <=800px
  - Small size reduction to navbar links (ticket #1996)

Imagegen:
- Theme tweaks

- Update some app icons
- Rationalise the markup
- Add tabindex ="-1" to icon links
  - This means they are skipped when using tab to navigate in the browser

which is a better place for it.

NewsManager should be a ClientApp, not a RouterApp

 - Enable new NewsManager to load/store feed items on disk by UUID
 - News items are stored forever, not lost when they are removed from feed
 - News read in once at startup, not at every summary bar refresh
 - Convert old initialNews.xml and news.xml to NewsEntry format
 - Limit display to 2 news items in summary bar, /home and /console
 - New /news page to show all news

Jetty starter: Register host/port when started
PortMapper: Add hostname support

     (unlikely as we don't show the "hide news" button for initial news)
     Also prevent string IOOBE

   - Fix NPE after restart (ticket #763)
   - Move more nonces out of system properties

The iframing pages remain accessible in the console, so this may be reverted in future,
or made configurable. The /webmail link buried in the text of the several readme.html
files has been left.
