Added MDO30 driver + Corrected small bug in PossibleBooleanList of all attributes: This list needs to be saved per channel and not one for all (hopefully it works now)

Added MSO64 (not completely tested) and had to make some basic changes because MSO64 has a slightly different cmd structure

TRied to clean up a bit (not 100% finished): Changed the inheritance structure; everything inherits now from a Tektronix base class (which can be used for 3ks)

Added class for MSO64 osci (working but needs more testing) and some files for TKDPO7k (not working / finished)
