Added destructive escrow. Tests seem to work out, but would-be-nicer if the contract
was more reusable
Basically rewrote the destructing escrow, and renamed it lockin escrow,
because if neither party budgets, the ether is locked in the contract.
Also a minor change to lib/sim.py to allow me to indicate the method myself
In refunds only the fraction paid, and the fraction merchant stake has to be paid
Added test for blocking changing the customer early
Added lockin-escrow.cll
flake8 conventions for lockin-escrow
Removed a flake8 warning on sim.py
Added contract.txs testing. Actually had to change max -> min which was a mistake..
Not yet checked coding conventions.
flake8, fixed forgotten fee
