[Feature] When populating the next game allow up/down to cycle through previous game names

It'd be nice if we kept the names/passwords of the previous 10 or so runs so after we are done muling w/ can just press the up key to go to the previous game name. For example if I join the following games in order
```
nm baal-110
xfer
```
the next game would be populated w/ `xfer`. It'd be cool to be able to press up to populate it with `nm baal-110`
