Save simulation info into permanent store

Create a file and save info (number of actors | tps) about every
simulation in it. If the file is already created it will just be opened.
Use raw transactions

Use raw transactions instead of SendFromMinConf. Also stop using account
balance updates since by using listunspent we can determine if a wallet
has funds to spend.
