[Feature] Put all TODOs onto Problem view

[jgclark]

Have an option that when running the List Annotated Highlights command, add results into the Problem tab, not the Output tab. Alternatively, have a new setting isProblem per highlight, that automatically adds them to the Problem tab.

Yes please! I'd also like if there was a setting so that the Problems view was updated when the project is opened and a file saved
