Enhancements:

- added the `align` parameter to all topbar widgets, allowing for individual widgets to be placed either on the left or right hand side of the topbar.
- Disabled QtChart’s context menu by default.

Bug Fixes:
- The `screenshot` method now works for subcharts.
- Tables will still render if a `NoneType` is passed to them as a value.
- Qt and Wx charts no longer throw an error when using the toolbox.
