A copy-paste error had snuck in.

Closes #222

Closes #223

Closes #220

The latter strips newlines in IE9

These make it possible to do code folding.

There is now a textWrapping option (default false, for backwards
compatibility) that, when turned on, will cause text to be wrapped.
Line-based cursor movement still moves through such lines one at a
time.

This is quicker to update, and allows querying both by height and by
line number, which will help with the text-wrapping and code-folding
implementations.

This fixes (mostly) vertical cursor movement in IE

Replaced "for" and "while" in indent tokens with "do".  This is not only simpler, but allows for correct indentation when "do ... end" blocks are used (these are valid; see the complete syntax of Lua: http://www.lua.org/manual/5.1/manual.html#8 ).

Closes #214

The callback in runmode currently returns for every token
only the text and the style. This commit adds the position,
the line and the character, to the callback. It's an object
with "line" and "ch" as properties.

A previous patch had changed the interface to markText, but not updated matchBrackets

Apparently, you can't set an invalid (by HTML3 standards) innerHTML in IE, so adding
<div>x</div> to a P element raises this very descriptive 'Unknown runtime error'.

Issue #215

It now moves, splits across lines, and merges properly.
