Tim Starling 4bb8a4c984 Updated Ace 
Updated Ace to the latest version of my fork on Github, i.e.
approximately 0.2.0 plus some improvements to the Lua indenting module.
I have submitted a pull request, so hopefully the next update will be
from upstream.

The suffixed file names (*-uncompressed, *-noconflict) have disappeared
from upstream, replaced by conditional compilation in separate build
directories. There's not much point in maintaining two unused copies of
the entire source tree, so I deleted them. To avoid migration issues, I
re-added symlinks in place of the suffixed files which were previously
referenced from MediaWiki.
