After running through the test procedures on Windows it was seen that the Dialog did not resize exactly as it does on *nix systems however, it was not ridiculously over-sized and could be resized by the user. If the current size that it automatically opens at becomes a problem for users then another issue should be written to deal with this, other than that I am happy to merge this.

Make FirstTimeSetup window slightly smaller

Automatic Bounding Boxes for Non-Axis-Aligned Shapes

Add weighted ls fitting system tests.

With these exceptions both tests seem to run ok on osx. This has no effect on win7 and
linux platforms. Hopefully it prevents a failure in the nightly builds (osx system tests).

Merge pull request #14394 from mantidproject/14379_implement_keep_open_checkbox_for_getNegMuMuonicXRD

Implemented Keep Open functionality in GetNegMuMuonicXRD

OptionalBool property widget

Script directories are not packages

MuonAnalysis window can resize its content now

Looks safe enough. Testing looks good. Will need a few iterations to hone via feedback.

Add IPropertyManager::getValue template specializations for const shared_ptr

Merge branch 'master' of github.com:mantidproject/mantid into 14379_implement_keep_open_checkbox_for_getNegMuMuonicXRD

Make sample workspace a histogram in SeqDomainSpectrumCreatorTest

Merge pull request #14422 from mantidproject/14368_fix_default_dimension_names_from_createmd_incompatible_with_maskmd

Fix default dimension names from CreateMD being incompatible with MaskMD

Somewhat frustrating new with VS 2015 different result from VS 2012. It appears to
be similar to that of linux (which I guess is good) - see what the build servers think

Improve workspace concepts documentation

Muon Analysis interface - clear data when instrument changed

Added progress report in algorithms: CreatePeaksWorkspace, CreatePSDBleedMask

Direct beam sort algorithm for REF_L works as expected. Files are correctly sorted.

Improve help sub category handling

On attempting a sequential fit, if the properties cannot be loaded, a
possible cause is that they have been cleared by changing the instrument.
Tell the user this, show them what the original error was and display
the error in the log too.
