Support for running multiple vibediff

[patrick91]

Sometimes I work on multiple projects at once and I'd like to be able to use vibediff within multiple folders.

Right now it is not possible to do that because vibediff tries to open the same port when running multiple times.

Can we make it so it either opens at a new port, or has a way to differentiate the current folder/project? 😊

You can use -port parameter to start it with different port

@malvex locally I made it so it tries to find an open port automatically :D
