Patched ruby 1.9.3-p125 for 30% faster rails boot

What is?

This script installs a patched version of ruby 1.9.3-p125 with patches to make ruby-debug work again (#47) and boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84).

It works with Xcode 4.3 and the clang compiler it ships with its command line tools package.

Huge thanks to funny-falcon for the performance patches.

	3. Styling of definition lists ala LaTeX description lists.
	4. Centering h1.title, h3.author, h4.date (pandoc's title/author/date block).
