Remove list of dependencies from README.

Note that the list was omitting jQuery even though it's currently used directly by the css plugin.

Relatedly, remove the line about manually installing jQuery since it's now installed automatically,
because it's used by the css plugin, since the 0714c2c change
to use jQuery promises.

That line should be added back if the jQuery dependency is removed from bower.json, if
requirejs-dplugins is updated to use lie instead of jQuery promises.
