Errors in pydsh - Allow RSA2 Algorithm to be disabled

[Former user]

If you are running v3.0.0 or later of pydsh you will get the following error message if the server you are connecting to doesn't support the RSA2 algorithm spec yet:

q must be exactly 160, 224, or 256 bits long

While the module allows this functionality to be turned on/off pydsh does not.

[Jesse Almanrode]

Added option to disable SHA2 hashes in SSH Connections when using pydsh

This should fix issue #21
