Wire Connect/Disconnect toggle button

[zvxvx]

I set the Button from display: none to show Disconnect when connecting to a network. Since this is done through useState boolean value, ideally this would trigger different functions based on the state instead: one for connecting (which exists) and another function for disconnecting.

A disconnect button needs to be added to the IRC component window. (I will probably add this) See connect function for details. There is a boolean state value there that turns to true when connected. Disconnect function needs to also include it to set to false to return to Connect component.
