Provider Log in - Can't change active Provider

When a Provider logs into the system, the active provider will always be themselves.  In addition, they will be unable to switch to a different provider.  Please see Notes for background on what we mean by this terminology if it doesn't make sense.

With Signature changes, this was necessary to keep everything in order.

SOAPware Provider's logging into the system.

When a Provider is created in SOAPware (via downloading from SOAPware licensing server), an associated user is created in SOAPware also.  This is the user account the Provider should be logging in with.  They'll need to be granted certain privileges to do much in the system first though.  So when we say a Provider logs in, we're assuming that they are logging in with the associated user account.  This link can be seen when editing the provider in Provider Manager.
