Turns out there is a difference between hg and git and I should not
switch that often.

Some pages need jquery in the head and instead of loading it twice on
these pages, it is better and easier to load it in the head on all
pages. It should be in the cache after the first load anyway.

I got feedback from many users, that they don't understand how the "my
activity" stream is sorted, because they have posts on the top, but
don't see why. The user doesn't see if a like was added, and it is also
not imported for the user to see the post again then. And we have
notifications if someone likes a users own posts, so no need to move it on
top of the "my activity" stream here too.
