- Fixed documentation typos

- In support of HMsec, allow the count command in countsec to run without a
  preset parameter. If this is missing the old, stored preset is used.
- Removed a check which causes initialisation of the HM from a batch file fail
  for POLDI
- fixed @nl@ encoding of \n problem with certain kinds of batch files generated by GTSE
- Fixed a bug with summing on hitsmemsec. nxdataset now uses 64 bit int for dimensions.
- Fixed motorsec to remove itself properly from a parent when linked. Please note
  that there is still the limitation that a second generation motor can only be linked
  once in a Hipadaba tree
- Extended subsampling a HM for second generation HM
- Added a hscriptnotify. This calls a script on the update of a node
- POLDI has been rebuilt, chnages to data file writing
- For testing, sinqhttopt now understands a special command, byteswapoff,
  which switches off byte swapping. Required when the HM ius run on an Intel box.
