new Cog VMs available

http://www.mirandabanda.org/files/Cog/VM/VM.r2678

CogVM binaries as per VMMaker.oscog-eem.264/r2678.

Fix snapshot primitive failure in the StackVM and Cogit. The

primitive should fail, not merely return the receiver. Also if in

Cogit, need to back-up instruction pointer on failure.

Make reportMinimumUnusedHeadroom more informative (also print

available headroom).

it may seem not to make sense, since unused headroom is > available headroom, but the system is measuring unused space in a stack page, and if a page hasn't filled up the portion used by Smalltalk (4096 - 3300) then the unused space will be > available headroom.
