If a node is ignored there's no need for searching for a given pattern.
In turn, when searching for the pattern there's no need to construct a
MatchData object as we only care about presence (or lack thereof), not
the resulting matches.

In terms of performance this cuts down about 200 ms when loading
issue #2164 locally, though this varies a bit depending on system load.

Fix duplicate repositories in GitHub import page

By default, all the current user's repositories are accessible via the
/users endpoint. There's no need to traverse all the organization
repositories as well.

See:

* http://www.rubydoc.info/github/pengwynn/octokit/Octokit/Client/Repositories#repositories-instance_method
* https://developer.github.com/v3/repos/#list-your-repositories

Closes #2523

Remove some padding from code blocks

This creates a weird "leading indent" on the first line of code blocks, at least in Chrome 46, and ends up making the first row not line up nicely with everything else.

Improve performance of sorting milestone issues

This will fix the problem described in #3066.

See merge request !1609

This cuts down the time it takes to sort issues of a milestone by about
10x. In the previous setup the code would run a SQL query for every
issue that had to be sorted. The new setup instead runs a single SQL
query to update all the given issues at once.

The attached benchmark used to run at around 60 iterations per second,
using the new setup this hovers around 600 iterations per second. Timing
wise a request to update a milestone with 40-something issues would take
about 760 ms, in the new setup this only takes about 130 ms.

Fixes #3066
