Image startup hooks

[Brian Rice]

Further note: this is in main, not alpha, but does not require any 
modified image or VM. Just start up one of the downloaded current VMs 
to have it load up this functionality. Once everyone's happy with the 
way it works, and ExternalLibrary is verified to be doing the right 
thing, I'll move it into alpha.
