Unuseful or disregarded frames should not be stored in memory and disregarded. If i'm doing a handshake attack, it shouldn't eat 16GB of swap for 4 frames listed on-screen after 8 hours of constant attack.

#189 will help users by giving them an easy way to connect to the node, but there are a number of methods of connecting that are not covered. I think all of those methods are better fit in a docs/help page where we can go into all of the specifics of adding a node/seed.

Currently if password is not set in the configuration, then there is no admin that is generated. We should ensure that this is a easy to see warning for the user, so that this does not cause problems later.

As a sidenote: This warning should be similar to the warning that we want in hstratum when there is no config. So a solution here also will be a solution for hstratum.
