Emulator ports should not be static

[jribbink]

Instructions

Emulator ports should be autofilled based on available ports on system. The end user should not have any context of what ports the emulator is running on as all of this information is unnecessary should be abstracted from their scope.

Problem

The emulator frequently runs into conflicts with these static ports such that it attempts to open the same port as an already running emulator.

The user should not have to deal with these issues as they ultimately don't care which port the emulator is running on - they just want it to work
