Implement config manager.

[kareltucek]

Moves all configuration to one central place, and thus allows global reset.

This does not reset component states.

How should I test this?

What do you mean by "component states"?

[kareltucek]

I mean macro engine state (scheduler state, macro states, possible static variables), mouse key state arrays, and other similar things.

[mondalaci]

How should I test this PR? I'm unsure.

[kareltucek]

Choose a settings that is not a part of the userconfig and does not edit keymap/ledmap in ram. Then write it from a macro (not a macro event). Now save configuration from Agent and test that the setting was resetted.

[mondalaci]

Please provide me with a couple of such example settings.

[kareltucek]

I am not at computer right now. I guess autoRepeatDelay, autoShiftDelay, chordingDelay, secondaryRole.advanced.triggerByPress, stickyModifiers, modifierLayerTrigger, oneShotTimeout may be of that kind, but please check that against Agent.

My trackpoint speed settings are disrespected regardless of the module section settings.

Ouch.

Fixed.
