Closed Feature: DH Key Exchange is limited to 1024 bit [1777]

DH Key Exchange is limited to 1024 bit.

Connections to a server with a higher DH Group Exchange bit-length failing with "An established connection was aborted by the software in your host machine.".

Received Message 34 on connection (PID 500):

----> did not find any matching group, giving up
--> error handling record, closing connection & bailing out


Bit-length should be increased in KeyExchangeDiffieHellmanGroupExchangeSha1.cs and KeyExchangeDiffieHellmanGroupExchangeSha256.cs to MinimumGroupSize = 1024, PreferredGroupSize = 2048 and MaximumGroupSize = 8192.

And it should be possible to change these with a property.
Comments: Fixed in 2014.4.6-beta2.
