fixed all the broken links to doc
Revert "fixed all the broken links to doc"

This reverts commit dd420ef187e83748daf5cd27a99c83ac5007e7b9.

The commit itself broken all the links in the documentation README when
the README was viewed directly (as intended). This meant people coming
to the documentation from the html5boilerplate.com site, or those
generating HTML from the markdown docs, were not able to view the docs.
Rename doc/README to doc/TOC

Avoid the problem with links in a directory README on github.com. GitHub
displays a directory's README when at the dir level, which results in
incorrect URLs when links are using relative paths. This is causing some
confusion for people who browse to the documentation on GitHub and try
to browse the docs from the automatically displayed README.
Add Apache configuration instructions for Mac
Remove outdated URL from .htaccess

Fix gh-1201
Update CHANGELOG
Fix `SymLinksIfOwnerMatch` typo in .htaccess

Ref. gh-1209
Add a `CONTRIBUTING.md` file

Move the information on contributing from the bundled documentation to a
new root file - CONTRIBUTING. This is both a more meaningful location
(not part of code documentation) and allows us to take advantage of
GitHub's latest UI changes that prompt people to read a repo's
guidelines before reporting issues or opening pull requests.
Enforce coding style in main.css print styles
Remove duplicate `markTimeline` from plugins.js

Fix gh-1211
Disambiguate chromeframe prompt wording.
Updated jQuery to 1.8.2

jQuery 1.8.2 has just been released. Google's CDN has not yet
been updated, but it shouldn't take too long before it is.
Merge pull request #1219 from ryanve/master

Disambiguate chromeframe prompt wording.
Improve `console` method stubbing

Avoid browsers with `console` and `console.log` throwing errors for some
of the other methods that they did not support.

Fix gh-1206
Close gh-1218
Update CHANGELOG
Fix `console` stubbing method in oldIE

Expose `console` object to global scope in IE6 and IE7
