Add plugin so far

I've added what I have coded so far. I still need to run it through
JSLint and write docs and a demo.
Formatting cleanup, based on JSLint output
Added a readme file.
Add demo page, minified version, and custom Modernizr. Adjust comments.
Fix typos.
Added link to demo
Fixed typo.
Add license info to readme file.
Bug fixes, update comments and readme

Fix issue where "more" link could sometimes be pushed out of view. Fix
wonky assignment for loop - it was harmless but pretty inelegant.
Clarified notes re: Modernizr in readme and comments.
Fix typo in comment.
Remove duplicate content from readme.

It was so nice I had to add it twice!
Remove wayward apostrophe from readme.
Automatically adjust menu on resize; add position: absolute to popups.

We now take care of adjusting the menu on resize and absolutely
positioning the popup. This should make the plugin a bit simpler to
use. It's no longer necessary for the user of the pluign to write
separate JS to resize or to add the position: absolute herself.
Added "menu" feature. Fixed demo in IE7.

Now, when there are only a few items remaining outside the "more" popup,
we'll move all items into the popup and change the link to "menu."
Fixed IE7 bugs in demo.
Update documentation.
Update minified version of script.
Fix bug that made links in popup menu unclikcable.
Collapse any other active flex Menus on page
Merge pull request #2 from 352Media/peteUpdate

Collapse any other active flex Menus on page
Update Demo to show multiple menus interacting. Fix bug that prevented menu from closing on click.
Changes based on JSLint. Update readme and comments. Use new jQuery. Increment version number.
