TUI Interface for Setting Server Address and Port

[Nitepone]

Current Implementation

Currently, it is only possible to select a server before the launch of client via launch option -a. Not supplying these causes the client to resort to defaults (a port on 127.0.0.1). This is quite confusing as there is no visual indication of what address and port is being used.

Proposed Enhancement

As a user, it would be preferable to be asked to set an address and port when opening multi-player mode. This should be done with a simple ncurses form that requests "port" and "address". The form should be automatically be filled with application default settings or what is supplied by -a.
