Moved fake dae back to ISISLiveData library.
For some reason it didn't work when in the same library with the listener. Re #7954

Re #7954. Added ability to vary the event rate in the fake DAE
to test how the listener copes with large amount of data.

- Status changed from inprogress to verify
- Resolution set to fixed
To tester:
- To be able to use the listener Facilities.xml must have an instrument which uses it. A fake instrument can be added:
<instrument name="EVENTS">
<technique>Single Crystal Diffraction</technique> <livedata address="localhost:10000" listener="ISISLiveEventDataListener" />
</instrument>
- Start FakeISISHistoDAE with NPeriods=1, NSpectra=1000, NBins=any value
- Start FakeISISEventDAE with NPeriods=1, NSpectra=1000, Rate=1 NEvents=10000. Numbers of periods and spectra in the two fake daes must match. FakeISISEventsDAE sends NEvents every Rate microseconds.
- Start Live Data. Set instrument to EVENTS, Update every 5 seconds, Processing: algorithm Rebin(100,0.1,200), Accumulation Method: Add, No post processing, At end of run: restart.
- Plot 2D and 1D, see the data change.
- Try the listener with different parameters.
- If NPeriods > 1 no processing will work. But a group of event workspaces will be created and members updated. This can be tested by manually rebinnig and plotting the workspaces.

This looks to be ok. Obviously this will be unable to test more completely until the correct version of the DAE is installed onto the event based instruments.

Noted that as planned, this does not yet support periods fully, or log data.
