Rework editing and diff showing

Clean build needs to happen before downloading pkgbuilds so that they
can be deletd before downloading.

Editing and diff viewing needs to happen after downloading the
pkgbuilds.

Prevously we asked to clean and edit at the same time. Then clean,
download pkgbuilds and open the editor.

This poeses a problem for diff viewing and editing. It's likley that the
user will see the diff and use that to decide if they want to edit the
pkgbuild. Using the current method, the user will be asked to view diffs
and edit before actually seeing any diffs.

Instead split cleaning diff showing and editing to three seperate menus
in the following order:
	show clean menu
	clean
	download pkgbuilds
	show diff menu
	show diffs
	show edit menu
	edit pkgbuilds

Also each menu is seperatly enableable. By default only the diff menu is
shows. If the user wishes to clean build, edit pkgbuilds or disable
diffs then the user can use the --[no]{clean,diff,edit}menu flags. This
replaces the --[no]showdiffs flags.
