Reslove MonitorData not showing in the workbench algorithm details box

This was due to:
1. Too long a default UpdateEvery default
2. Too infrequest progress updates from MonitorLiveData
3. The Algorithm Details box not adding an algorithm until it sends a progress update
4. The StartLiveData custom Dialog not showing the default for UpdateEvery

1. Decreased the default UpdateEvery from 60 to 30 seconds
2. Change the default timeout for FakeISISHistongramDAE from 30 to 60s
3. improved the progress logging for MonitorLivedata to update more frequently with an idle counter as well.
4. Changed the tie function used in custom algorithm dialogs to set the placeholder text for line edits
5. Changed the log level for user cancelling of algorithms from Error to warning so it does not trigger the notification service
6. Changed the log message for user cancellation from Terminated to cancelled to reduce confusion

- An exclude property has been added to the fit property browser
- The images tab in figure options no longer forces the max value to be greater than the min value.
- Double clicking on a workspace that only has a single bin of data (for example from a constant wavelength source) will now plot that bin, also for single bin workspaces a plot bin option has been added to the right click plot menu of the workspace.
- Default values for algorithm properties now appear as placeholder (greyed-out) text on custm algorithm dialogs.

- Running an algorithm that reduces the number of spectra on an active plot (eg SumSpectra) no longer causes an error
- Fix crash when loading a script with syntax errors
- The Show Instruments right click menu option is now disabled for workspaces that have had their spectrum axis converted to another axis using :ref:`ConvertSpectrumAxis <algm-ConvertSpectrumAxis>`. Once this axis has been converetd the workspace loses it's link between the data values and the detectors they were recorded on so we cannot display it in the instrument view.
- MonitorLiveData now appears promptly in the algorithm details window, allowing live data sessions to be cancelled.
