as stock, upon exception show message box and kill discord.

[Skamt]

turns out when the renderer process crashes nothing happens and it stays running in the background, as OA is missing exception handling around the renderer like in stock discord.

This shouldn't use try catch, instead use process on uncaught exception/etc

[Skamt]

without the renderer's dedicated try catch, if something breaks early the update's try catch catches it and discord gets stuck in the splash checking for updates.
it would require a lot more changes to remedy this, and i try to keep my PR as small as possible, if you think this change is no good, you can close the PR no problem :)
