Allow manual resize of js-autosize textareas
First, the autosize library was being too controlling and removed the
`resize` property from any elements to which it was attached, removing
the drag handle. We've disabled this behavior in the vendored library
and added a spec to prevent a regression during an upgrade.
Second, we detect (as best we can) when the user manually resizes an
autosize textarea, and then remove the autosize behavior from it and
increase its max-height.
This should allow for the best of both worlds.

Highlight note code and edit preview
More highlighting fixes! Highlighting wasn't applied all the way for
code in notes, diff notes diffs and diff preview (on the file edit page).
The CSS changes further unify the styling for file-content highlighting,
diff highlighting and note code highlighting.

Fixes issue where firefox does not delete message after comment submit
Issue was **not** in the way comment was being submitted.
`app/assets/javascripts/awards_handler.coffee` was throwing an error.
This error was preventing any js from running after it.
Fixes#1473

Issue page keeps jumping up
This happens when the discussion side is smaller than the sidebar and the sidebar will need to scroll. When this happens I calculate the height of the two and see if the discussion panel is smaller and make them the same height and add a class `no-affix` which makes the sidebar relative positioning so it won't stick to the top.

Since GitHub doesn’t apply these constraints to theirs wiki slug
allowing characters like `,`, `:`, `*`, etc, we need to relax our
constraints or some wiki pages will not be available after they were
imported.
For an example the Devise project have a wiki page with the following
slug: “How To: Add sign_in, sign_out, and sign_up links to your layout
template”
Refactor ZenMode
- No longer depends on the "hidden checkbox".
- No longer depends on manually storing/restoring the scroll position.
Instead, we take advantage of jquery.scrollTo.
- Event-based.
- Simplifies the state-based styling.

This ensures the dropdown is fully available the moment a user starts
typing out a username, issue ID, etc. While this won't speed up loading
the autocomplete data itself it should at least make it less annoying
for the user.
