Refs #8700. Adding logs to *_Workspace when doing a single fit.
Refs #8700. Adding a logs to *_Workspace in seq. fit.
Refs #8700. Change the way list of fitted workspaces is retrieved.

Now we just take a list of all *_Workpace workspaces and work with
them. Original data is not required anymore.
Refs #8700. No need to store loaded seq. fitting workspaces.
Refs #8700. Minor code clean-up.
Updated wiki documentation. Refs #8720.
Fix incorrect use of property declaration. Refs #8720.
Update property documentation. Refs #8720.
Do not save the workspace history to a file. Refs #8729.
Correct documentation. Refs #8720.
Merge remote-tracking branch 'origin/master' into feature/8720_generatePyScript_documentation
refs #8732. Documentation should show up now.
Updated documentation. Refs #8720.

- Made clearer that generatePythonScript can output the content into a variable OR Python script file.
Merge remote-tracking branch 'origin/feature/8720_generatePyScript_documentation'
Use error message returned from IDS. Refs #8730.
Refs #8731. Disable Peak Picker tool when Fit Prop. browser deleted.

Otherwise need to do that manually in MuonAnalysis, which is very
error-prone.
Refs #8731. Minor refactoring.
Refs #8731. Toolbar hiding as signal.

We don't need it to be called instantly and this avoid the kinds of
problem we faced in a ticket. Things in hideEvent and showEvent should
ideally just emit queued signals.
