Previously, lists following other content weren't always highlighted.

Per Dingus.

Should use `em` or `strong` instead.

Add support for nesting and avoid hiding code highlighting.

Related to #1276 (but blockquotes, instead of lists).

Also includes improved support of nested lists.

Closes #1276.

Closes #1290

+ add CodeMirror Movie link

And use the editor-wide option when no value is found on the mode.

Issue #1281

The old mode was not supporting many rST constructs, or not in
sufficient detail. Features/changes:

 * no `backUp` ops to keep things fast;
 * kept `python` inner mode integration;
 * added `latex` inner mode;
 * eliminated `verbatim` configuration parameter;
 * eliminated non-standard tokens: the old mode was producing `footnote`
   and `citation` tokens, which were replaced with `quote`;
 * many more details: visually compare highlighting between old and new
   to get an impression;
 * MIT license (copied and adapted form `python` mode);

A call to replaceRange hadn't been updated to its new signature.

(but only remotely).

It fails on Travis, but not on my local machine's Phantom or in a real
Webkit, so I'm going to assume it's a spurious failure.

Issue #1268

- handling special keys better for commands requiring a character
- r can operate on selection
- fixed: t moves back if character not found
- +/-/_ via extension of moveByLines motion

No full measurement is needed, since most of the time the longest line will
be scrolled out of view, and we're only interested in its length.
