News: dscan, ctrl-c, fio_recorder; SardanaMonitor3 and Ctrl-C in spock; toPyspMonitor() with zmqPort; pyspMonitor, door specification; TngGui msProperties.lis; TngGui.py also for non Sardana ExpPCs; various open points

dscan, ctrl-c, fio_recorder: interrupting dscans which write .fio files with Ctrl-C caused this exception: ScanException: error while restoring a backup. Has been fixed.
SardanaMonitor3: interrupting scans with Ctrl-C while the SardanaMonitor3 (Debian-10) is running screws-up the MacroServer. Status: solved.
toPyspMonitor() using a specific zmqPort allowing one or more other pyspMonitors to run to display results.
```
 
pyspMonitor.py -p 7780 -n
```
The argument '-n' tells pyspMonitor not to connect to a door.
An example can be found here
Note that this function is available under PySpectra.toPyspMonitor() and also under HasyUtils.toPyspMonitor(). Reason: toPyspMonitor() should be callable from Macros. But Macros may not import PySpectra because this may lead to a PyQt4/5 conflict. Therefore, use HasyUtils.toPyspMonitor() in Macros.
pyspMonitor.py allows for door specification, see here
TngGui.py, changed feature: the action Files-MacroServer-Properties creates a versioned, humane-readable file /online_dir/MacroServer/msProperties.lis (and launches an editor).
From the command line: TngGui.py --mp.
Facilitates the Debian-10 transition.
TngGui.py, now also for non-Sardana BLs
SardanaMacroExecutor, stopping macros: it is not possible to stop a Macro which is executed by the MacroExecutor by Ctrl-C from a spock session.
Workaround: use pyspMonitor or SardanaMonitor to stop/abort Macros or use spock:
```
spock> door.abort()
spock> door.stopmacro()
```
p021user, gamma portal, meta data also for ongoing beamtimes. gamma portal updated after 1 h.
P06, stopBeamtime, grace period for beamtime user too should be 2 weeks, AR will discuss with JG.
P64, dscan exp_dmy01 -0.1 0.1 10 0.1, divide-by-zero for certain attributes, wait for new sardana release
P65 taurus cannot move motors to 0. Solved.
