Fixed some things in README.md (using Java 7 and `gradle jettyRun`
instead of `runJetty`).

Removed site/ from repo since it's generated. Added .gitignore ignoring
build, site, and .gradle.

Added `outFile.getParentFile().mkdirs();` to Main.processTemplate to
make the dir `site`'s existance unnecessary i.e. it will be created if
it does not exist.
Used spaces instead of tabs in Main.groovy
