Report errors more gracefully

[helgoboss]

Show "ERR" in menu bar when a serious error occurred and show error report when pressed. Needs REAPER 7.27+dev1103+.

Ah no, that needs more work. Errors go unnoticed way too easy like this. Should probably be an opt-in for users that really want to suppress errors, no matter what.

I can imagine a (ideally non-modal) window popping up on the first error, asking the user how to proceed:

• Auto-send to developer (that would be a new option)
• Pop up error in console

And maybe a warning message if none of this is checked that Helgobox needs to know about errors to make improvements.

The settings should then be saved.

Also, the backtrace should NOT be captured if both checkboxes are unticked. Because capturing the backtrace can freeze the application for a sec, especially on macOS.

Implemented it like that. The checkboxes are part of the welcome panel.
