The most recent update replaced the minimal image with a large one for the
'generic' image. Switching back to 'minimal' should reduce dependencies and
maybe speed us up some.

It should also eliminiate the need for aa2e0f0.

Note: TX71 no longer has a state.  TX71 enables & TX72 disables.

Note: during some testing I picked up that while loading the freeze state at startup if there are multiple freeze/unfreeze transactions in the same block they may not be loaded in the correct order.  Unlikely scanerio but we need to cover it just the same.  This change just adds the tx position within the block to the sort order.

Note: addressBytes size check failed (didn't include version) so was never truncated to remove checksum.
Note: also removes "unexpected size from DecodeBase58 when decoding address" erros from log.

Note, freezing should only affect the available balance, not prior actions

The following steps could be done by anyone and would have tripped the assert:
1) List a trade from address A for prop N
2) Freeze address A for prop N
3) List a matching trade from address B

Note: Behaviour of AbortNode() can be inconsistent and we cannot be sure of the state the client will be left in.  During testing it was possible in some circumstances to simply restart the node and continue on after a forced shutdown.  This change destroys the persistence state to force a reparse in this case.
