add master_sign_key_name and generation of the actual sign-key-files if activated
make MasterKeys() more flexible by allowing different key-names.

MasterKeys() should be able to handle more than one hardcoded key.
The default is still to just handle master.* files but can also generate
new key-pairs with different names and return the pub-key.
fix join()'s to form the correct file names
add key name to logging output
add settings for master and minion to sign the public / verify pubkey signature

Add a setting for the master to generate a new signing key-pair for signing purposes
and use the key-pair to sign the masters public key that is send to authenticated
minions.

Add a setting for the minion to verify the signature of a public key received from
the master. Requires to have the signing key-pair from the master on the minion.
Add optional signing of the master pubkey if enabled in config.

Uses salt.crypt.sign_message() to create a signature of the pubkey
and adds that signature to the payload send to authenticated minions.

Adds the verification of the master pubkey by checking the pubkey
signature in payload['pub_sig'] with the signing keypairs pubkey.
