Add Sentry Error Tracking

[breadbyte]

• Added a notice that we're using Sentry when first generating the config file
• Added a config option to disable Sentry crash logging

Currently sends information about the current .NET Runtime and the Operating System. Here is a screenshot of all the information that is sent to Sentry whenever a crash occurs:

Currently uses my personal DSN. Will need to change that to our DSN before merging.

Haven't looked in to the code, so you might have already added this. But it would be a good idea to allow this only for binaries that we release here, because someone could modify the code and cause an error.

We could put the DSN into repository secret/variable and populate the DSN during build-time, just like how we populate the build info. Correspondingly, the code would need to check the DSN string before initializing Sentry SDK.
