allow cmd sequences in verb execution

The syntax changed. Instead of `execution` (which is still allowed),
`internal`, `external` and `cmd` are now prefered.

The syntax of the `cmd` property is the same than the `--cmd`
launch argument, with the added possibility to have dynamic parts.

Two examples of sequence based verbs:

	[[verbs]]
	name = "myplaces"
	key = "ctrl-g"
	cmd = ":focus ~;:!focus /"

	[[verbs]]
	name = "backup"
	invocation = "bu {name}"
	cmd = ":cp {file}-back_{name};:!focus {file}-back_{name}"
	apply_to = "directory"
