Widget\FilterWidget: ui cleanup
Ido\CommentQuery: add host/service shortcut column
Monitoring\Controller: add $url to all views

There are too many view scripts fiddling with namespaces. There is
still the url helper, not sure why it's not going to be used. I may
roll this back one far day...
timeUntil/timeSince: add timestamp hover title

It's sometimes easier to read "full" timestamps.
CSS/tree: add CSS support for simple tree views

Not sure whether we should replace this with a "flat" one, it should
do the job right now.
CSS: Show filterEditor as a tree
CSS: fix cursor size in chrome

This has been introduced by fixing IE8, line-hight==input-heigt looks
ugly on chrome.
monitoring/downtime: add missing ticket hook

We used to have this when showing comments, but not for downtimes.
Web\Url: small fixes, allow override queryString
