Enable tables inline-editing in lazy-loaded tabs

Previously inline-edit was initialized only the first time the page
was loaded which had been preventing inline-edit for the tables which
were inside lazy-loaded tabs (i.e. loaded with AJAX-request). Fixed
that.

Fixes the Order of "launch" buttons on jobs panel

On the data processing/jobs panel, the first "launch" button is "Launch
on New Cluster". This patch make the  "Launch on Existing Cluster" as
the first button. "Launch on New Cluster" is moved down on the list.

Also when "Launch On Existing Cluster" becomes the default option, the
"down arrow" to expand the action choices wraps down to the next line.
So added css to fix this issue.
