Layout handling in travis-web was implemented in a dynamic way, so we
could change a main layout from any of the routes. This needed a
`rerender` call which was making things harder and needed some hacks. It
also broke a few transitions when upgrading to 1.8.1.
After examining our usage of layouts I've noticed that we don't need to
change the entire layout dynamically and instead we can set layout on
root routes (like "index", "profile" and other root routes).
I found the commit that caused the bug that caused me to do the last
revert. I'm therefore reverting the previous revert and I will be
committing a revert that reverts the commit that introduced the bug. See
next commit.
This reverts commit db2d38a7af.
This commit contains a settings pane implementation. There are a couple
of things here, which are not used yet, like advanced form helpers. I'm
leaving them here, because the plan is to add support for more settings
soon (like: include/exclude branch patterns), which will need these
helpers.
There is also tabs support, although in the current version there is
only one tab (initially it was created for supporting general tab and
notifications tab).
