Choose on which corner to display Frame/Stim markers

[Antonin Blot]

For now frame marker is at the bottom right and stim marker at the bottom left. It would be nice to be able to change the position without hard coding it.

I'm not sure we can display stimmarker without showing framemarker. That would also be useful.

The pull request https://bitbucket.org/DylanMuir/stimserver/pull-requests/2/frame_marker/diff should solve the first part of the problem: select which markers are used
