Allow users to give controllers aliases

[jsbackus]

We could allow users to assign different controllers (based on GUID) an alias. If none specified, fall back to SDL name. This would resolve confusion on systems that use Xinput, since everything is a freaking "XInput Controller"...

AntiMicro is no longer maintained. There were no bigger fixes since 2017.
There is a new recommended version of this app called AntiMicroX.

As a part of cleanup, this issue will be closed and repository will be archived.
If you find this issue relevant also for that new version of application you can create a new issue (or discussion) there (but firstly check it, because many issues of the old app are fixed and there are some new functionalities implemented)
If you will decide to create a new issue for AntiMicroX remember to mention this issue for reference.
