The issues were all around Safari. The logs toolbar didn't display pod name; now it displays.

Fixes: #828

Fixes #771

1. Sorry for the size, but this PR was all-in or nothing
2. The mechanics for namespace is that user selects it via the dropdown
   and the selection goes through all pages, but has effect on display
   only on list pages.
3. The selector is now ugly. I'll style and improve wording later.

This is in preparation for brand-new CI setup where we run karma and
integration test against all major browsers (IE/FF/Chrome). With this
change the tests pass.

Also, make some changes to the api to allow for omiting specification of container.

Previously podst that weren't in the phase of success were displayed incorrecty in lots of places.
