Option to disable swapping to new errors

[kaedys]

Bugsack automatically swaps to the error page for any new errors that come in. Especially during prepatch, when I'm trying to debug and find fixes for a bunch of my addons while waiting for the authors to get everything up to date, it can be incredibly annoying to constantly have the window swapping back to one of the errors if it is firing regularly, when I'm trying to debug a completely different error/addon. It'd be nice if there was an option to disable this behavior.
