Allow supplying custom profiles

[MIJOTHY]

It looks like the set of profiles used in dependency calculation hard-codes the profile being used:

vizdeps/src/leiningen/vizdeps.clj

Lines 218 to 220 in e106df5

	(let [profiles (if-not (:dev options)
	[:user]
	[:user :dev])

It would be useful if consumers could supply profiles, either via the usual lein with-profiles foo <command> syntax or through a command line argument.

Happy to submit a PR.
