acq2 server bugfixes and rawTransfer option

Allow user to transfer only the corrected acq to the server, without
copying over the home directory. Default is still to copy over home
directory.
segmentConsensus modification

Disabled parallel processing of the segments, so that parallel
processing is passed on to the motion correction interpolation function
which uses parfor over the movie frames. At least as fast, maybe better,
and makes better use of superlogics computers with more than 6 (e.g. 12)
cores
