- new method scaleWorkspace which reinserts Dx values for point data
- deleted MantidDataObjects/WorkspaceSingleValue.h from Multiply and Divide
- introduced new class variables m_scaleFactor and m_errorScaleFactor; those values will now be initialised by 1.0 (the default value) and not 0.0 as before.
- deleted unused tool-tip texts (Optional.)
- ConjoinXRuns output workspace property is a Workspace and not a MatrixWorkspace -> dynamic pointer cast
- unit tests for histograms pass
- MantidPlot executes for point data example from unit test
- unit test for point data fails (SortXAxis, Python algorithm, not registered!)

D2B detector efficiency calculation

Fake dae responsive cancel

MonitorLiveData now cancels more quickly so the tests should not fail

This guarantees that background algorithms get
cancelled should StartLiveData raise an exception

Includes:
  - using stack allocation for tcp server
  - removal of unnecessary mutex
  - unused includes removed

Adding beam stop arm masking for all ISIS SANS instruments

If the source stops sending data then the cancellation
request has to wait until the receive loop completes
before it is checked. Add the check in more places
to improve the responsiveness.

Update OFFSPEC Parameter File

Add script to build dev site

Updated print statement to python 3 in SaveWorkspaces

Force higher compression xz format

ConjoinXRuns can receive input workspaces containing Dx values

Updated if statement in ExtractMask to work with MaskWorkspaces

- put each declaration of a variable in a single line
- using const auto  & to get x, y, e, dx
- directly set the size and xerrors in setPointStandardDeviations
