Uifixes

Running my own CI on buildbot nine, I did find a bunch of issues in the UI. This also includes #1231 

misc fixes to the UI
- fix breadcrumbs
- add breadcrumbs on more pages
- make logviewer full screen
- automatically create slugs for logs
- fix log url (name vs slugs)
- display durations in build summaries
- fix rotation animation on chevrons
- fix mq event matchers (it matched too much events, resulting in weird update in UI)

`loog` is ugly, for sure.  I think `log_` would be a more common idiom (leading `_` indicates private; trailing `_` indicates "this identifier was already taken").  I don't like `logger` since that's not what it is.  So I'd say either `log_` or `logObject`.  The other option is to rename the `log` module to `twlog` with `from twisted.python import log as twlog`.
