Remove api bar from RightAllDBsHeader

This expands upon Christian's work and removes the api bar component
from the RightAllDBsHeader. It mimics Christians work for the documents
module.
Move parts of fauxton.less to templates.less

Fauxton.less is pretty hot code when you look at the commit
frequency. This commit just moves the parts of todays
fauxton.less to the new templates.less file to avoid a
long living branch with endless merge commits. This way
my colleagues can already use the new templates.less file
and have the advantage of a small separate template.less file
as soon as possible.
