This patch changes the module's description in the .info file

I've long thought that jquery_update should tell me what version of jquery my site is running. Right now, it does so on the sitewide status page, but what about on the admin/build/modules page too? After all, this module is statically tied to whatever version the jquery.js file happens to be. It's not like that version number is going to change dynamically whenever the jquery code is updated, and I don't see official releases of the jquery_update module coming out every month, so I think it's safe to write the jquery version number right into the .info file.

If the jquery.js file is changed to a new version, the .info file text just gets updated before the next release is pushed out the door. We might have, say, one more release of this module ever, so I don't forsee this as a huge burden on the module maintainer.
