add function for disabling mouse/key/wheel/signal bindings

currently there are a lot of workarounds for inhibiting these bindings,
but it's getting harder to keep track of all the conditions and cases
where bindings need to be worked around

this should greatly simplify the process of toggling binding activation
in cases where such behavior is undesirable

acpi bindings are always allowed since they are unlikely to interfere with
operations where direct-input bindings would be harmful
