This pull request introduces a new feature to the RebinRagged algorithm and includes updates to the documentation and tests. Additionally, it addresses a bug in the colorbar widget used in the Sliceviewer. The most important changes are summarized below:

RebinRagged Algorithm Enhancements:

• Added a new property FullBinsOnly to the RebinRagged algorithm to allow users to omit the final bin if its width is smaller than the step size. This change affects both the initialization and execution of the algorithm. [1] [2] [3] [4] [5] [6]

Documentation Updates:

• Updated the RebinRagged documentation to include an explanation of the FullBinsOnly parameter and provided an example of its usage. [1] [2]
• Added a note in the release notes to highlight the new FullBinsOnly feature in the RebinRagged algorithm.

Testing Enhancements:

• Added new tests in RebinRaggedTest.py to verify the behavior of the FullBinsOnly parameter for both event and histogram workspaces.

Bug Fixes:

• Fixed an issue in the colorbar widget used in Sliceviewer to allow the registration of custom matplotlib colormaps in scripts. This involved updating the initialization of the colormap list and handling potential errors when setting the colormap. [1] [2] [3] [4]
• Updated the release notes to reflect the bug fix for the colorbar widget.
