Added templating support through new --ks_meta option which works like --kopts. The parameter is a space delimited list of key=value pairs, which allows the variables entered to be evaluated through Cheetah. Thus kickstarts are now Cheetah templates. All templating errors are ignored so usage of a $ in a template is still legal where it doesn't reference a variable. Error ignoring should be finer grained and this does need some tests. Currently this only works for kickstarts on filesystems, and I'm not sure what the behavior for http and nfs should be. Anyhow, fairly useful stuff.
