doc attr folding and comment tag stripping
always call remove_comment_tags when needed
Slightly reorganize clean

Makes it so that impls are next to their struct
Extract crate name and attributes

Crate name extraction is currently broken; it needs an explicit
 #[link(name="foo")]. I couldn't figure out how rustc infers crate name... I
think it just looks at the basename and strips the extension but I'm not
positive.
Generate module trees rather than a flat namespace
Update readme with overview
Merge branch 'master' of https://github.com/cmr/rustdoc_ng into working

Conflicts:
	clean.rs
Slight restructure and (untested!) plugin support
More complete argument handling and rustc update

Now handles closure arguments (very incorrectly!) and basic argument name
extraction. And yes, I rolled up the update to rustc master into this, because
I am too lazy to do a proper git commit -p.
