Aw: How do I clear a textarea instance?

I have just pushed a commit that adds a generic function reset, which
first clears the textarea (field, form) with the background char,
then resets the internal variables.

In the default keymap, it is bound to ^R, but you can change that if
it doesn't make sense to you.
