I've resync'd with your repo

Vann,

Thanks for accepting my updates. And thanks for writing this plugin, in the first place!

Well, I rebased my latest changes on-top of your repository, so you can pull my changes again (assuming you want them ;-))

My latest changes include:
(1) bug fix(es) to the rake task -- I believe I added some bugs that I failed to test until after I pushed
plus, I'm using standard rake task input notation (instead of, for example, setting the LIB environment variable, you simply pass the values in square brackets:
rake gajax:install[jquery-1.3.2]
)

(2) support for multiple versions of a js-lib
I needed this for my project, where (sadly) our admin and user interfaces use different versions of jquery.

(3) updated docs

Again, don't hesitate to let me know if you disagree with any of my changes. I'm certainly open to feedback.

Cheers,
Jonathan
