Renames site-wide.scss to site-wide.sass

It's actually SASS, not SCSS, which confuses the tools.
Applies .css-only changes to .sass file; regenerate .css

Since we have the SASS, we ought to update that and then compile
the CSS from that. A couple recent commits didn't do that; this
patch applies them in the SASS. I regenerated the CSS file with
those changes.
Makes H1 headers big 'n chunky.

This is really just my personal style opinion... But the existing
H1 styling didn't look all that more imposing than H2 tags, except
for the capitalization. This feels more weighty for top-level use.

Chunky H1s
Make Twitter and RSS widgets more compact

This should make it easier to shuffle these around on the homepage,
but it also tries to make the news look a little more prominent.
Extended overhaul of main page

- H2 slogan is updated based on Mo's pull request
- "What is Aeolus?" content spans full width; totally rewritten
- News and Twitter content sits below content
- Twitter widget colors now blend in with site color scheme
- 'For Developers' section is removed; it didn't make a lot of
   sense on the homepage, and conveyed little actual information.

Homepage revamp
Removes imagewarehouse.html page, footer link, and inbound links

This project is not actively developed, or even actively _used_
by Aeolus in current releases. The page it linked to had a single
sentence, so the thing should just be removed.
