Removed 57600 from Jee auto baud selection

Removed sooner rather than later, may cause some early rf69 adopters a
problem. But this is the better time and the consequence is quite small
as the auto selection can be overridden by defining the baud in the
interfacers settings in the conf. marked version as rc1.2
Marked new version before new commits
