mintM(mintId)
Callable by minter approved by TTG who is not frozen at the moment
Executes the mintId created by proposeMint()
Checks that mintId is still executable by verifying that now>=mintDelayANDnow<=mintTTL
Checks that minter is still sufficiently collateralized: (CVminter−totalPendingCollateralRetrievalsminter)∗MR>=activeOwedMminter+amount
NOTE: If CVminter was not updated on time, the protocol assumes that it is set to 0
Deletes mintId proposal
Updates totalActiveOwedM and activeOwedMminter
totalActiveOwedM+=amount
activeOwedMminter+=amount
Mints amount of M to destination address
Calls updateIndex.
