Add functions for manipulating Caret position in text fields/editable divs/etc.

There is a big inconsistency between browsers and the ability to manipulate this can be invaluable for many applications.

This would probably be great as a plugin, but I really don’t think it should end up in the core library.

There already is a plugin: ​http://www.jquery-plugin.buss.hk/my-plugins/jquery-caret-plugin

It's worthwhile functionality, but I am also not sure 100% if this should go in core.

Since there's an existing plugin to address the need and it's non-trivial in size, let's just continue to point users to the plugin.
