Function: withdraw()

Extracts all the issueToken tokens from the contract. Only callable by the owner. All stakes are invalidated by setting the cut-off between valid and invalid stakes (indexStar) to the current indexEnd. Currently, this is off by one, as indexEnd is supposed to always be one more than indexStar.
