v2.1.0

Convert the datastore write "pauser" to be a "transaction"

This is to mitigate the possibilty of race conditions when writing multiple values and trying to read one of them. For example:
thread 1: begin transaction
thread 1: write is_account=true
thread 2: read is_account and account_username; get true and ""
thread 1: write account_username="blah"
thread 1: commit (or roll back)

The new implementation will require thread 2 to wait until thread 1 has finished its transaction.
