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)

I realize now, that this is an api, another rename of log is often loog, I believe this might be better
