GreenSQL-FW: 1.1.0 released

GreenSQL 1.1 is primarily a bug fix update of the previous GreenSQL version. One of the main fixes is to ensure code compliance with the MySQL version 5.0 protocol. During the MySQL protocol handshake, we disable MySQL built-in compression and encryption as GreenSQL does not yet support them. Old versions of GreenSQL were not aware of the compression and encryption at all, so by disabling them, we are able to check and forward the database queries.
