Merge pull request #259 from rjackson/update-ember

Update to Ember 1.4.0.
Make "to top" link visible when scrolling through the log

These are the changes by @dmathieu (reverted at d7bef2b) slightly
changed to allow us to use them also on Travis Pro.

The change is to still use onScroll calculations in order to position
elements instead of using "position: fixed". The latter method is harder
to use when element needs to be positioned relatively to other element -
on Pro we would have to still calculate the position because of the
right sidebar.
Remove unneeded console.log
Use outerheight when calculating position to take padding into account
Update pusher to 2.2.0-rc2
Provide more copy for insufficient oauth permissions.
Make explanation box smaller, left-align text.

Calculate position of #tail element rather than setting position fixed

This change ought to be commited along with 535a873, but due to a bit of
chaos with reverts and merging it's not in the master branch. This fixes
a position calculation of #tail element on the log to work even with
right sidebar (which is a problem on Travis Pro)
Use link-to instead of the deprecated linkTo

These were mostly removed in 8d681e85affc5abcb283d95de783e9fe14383fba,
but some where left over.
