fixed ChangeLog for 0.6.1

accidentally the ChangeLog entry for 0.6.1 had been merged into 0.6.2
reformatting to kernel-standards
break lines

to make lines shorter than 80chars
remove commented out code
don't implement STD-ioctls

these ioctls don't make sense for webcam-like devices, e.g. v4l2loopback
LATER: probably they do make sense, e.g. if a producer wants to
provide a given standard
don't STD capability
