History overlay cosmetic bug fix and test case update
doc: updates instructions

More dependencies, and the information moved to the doc/develop folder.
Replaced relative stage movement with absolute movement on Overview mouse clicks. (Relative movement was  given weird results, because the user could click a new position while relative movement was already taking place)
Merge branch 'master' of vpn.delmic.com:odemis
driver tmcm: update comments

I now know the position of the 2 temperature sensors.
driver pigcs: make it possible to do moveAbs with closed loop and not referenced.

The expected behaviour of the actuators in Odemis is that if it's not referenced,
it can still do an absolute move, assuming the 0 is at the starting position (or
a fixed position at least).
Fix *wip*
odemisd: fix log file rotating multiple times in a row

due to multiprocesses, the RotatingFileHandler would be duplicated, and
when a log reached the limit, it would be multiple times rotated.

So instead, keep things simple, and rotate manually, just at the beginning.

The more fancy way would be to set the loggers to a pipe, and have this pipe
saved into a file (and rotated) in a separate process. For now, simple should be
enough.
