Make mouse distance limit event handler dependent

[jsbackus]

Current movement range limit of [-127,127] comes from vmulti, but this value appears to vary across backend implementations. See conversation in #105 for more info.

AntiMicro is no longer maintained.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.
