Introduce gesture recognitiondevs/bu5hm4n/recognition

This is currently using libinputs gesture recognition. And offers a
config screen to setup new gestures.

1. No default gesture bindings are setup

2. When libinput is not available the module is not going to be loaded,
   and nothing is recognited.+

3. Only swipe gestures are recognized yet.

4. For now, you are required to be part of the input group, otherwise we cannot
   get the libinput events. (See Todo 1)

5. The visual representation is not really good. In terms of UI, it is
   visually showing a value coming from left to right, which is
   indicating a direction, which is not always the direction of the
   gesture, which is kind of bad. More improvements needed here.

Some things that still can be done:

1. The whole libinput things should be handled by elput, either with the
   input group hack, or logind, or simply by root. The ideal idea would
   be that e_sys is creating the elput context, which also listens for new
   devices etc.. When all this is done, and it recognizes a new device, it
   can simply sent a message from e_sys to e, that there is some new
   device, with a opened fd. (However, this all needs to be locked up in a
   way that e_sys cannot be abused)
