Romain Bazile f27c9823a1 Integration of raspimjpeg ...

The source code of the modified version of raspimjpeg used by the PlanktoScope is hosted [here](https://github.com/PlanktonPlanet/userland/tree/master/host_applications/linux/apps/raspicam).

We moved away from picamera to improve the stability of the system. This commit should closes the elusive #51 and #54.

After a lot of tests, it was clear that even a forked version of picamera was not going to solve our problem while also improving on our capturing speed.

The modified version of RaspiMJPEG does that.
RaspiMJPEG streams the image flux to /dev/shm/mjpeg/cam.jpg . This is passively reloaded by the streaming server (still written in python).

RaspiMJPEG is controlled through a special file called a Pipe which is used to send it commands.
The list is available [here](https://github.com/PlanktonPlanet/userland/tree/master/host_applications/linux/apps/raspicam/Config.md).

The raspimjpeg binary is distributed directly in this repository, in the folder `scripts/raspimjpeg/bin/`.
