Subject: [PATCH] [BREAKING]: Receive injected cashay

Allowing the user to provide the cashay package reduces the size of this
package and puts the user in control of which version of cashay they are
using.  The downside is that we must keep a close eye on version
compataibility, and this may or may not be anti-pattern.
