Changes to the auto-reporter

[Earthcomputer]

Currently the auto-reporter is spammy which makes it hard to process the actual issues.
I propose the following changes to the auto-reporter:

• Edit existing issues to specify the number of times it has occurred, and update the OS/IntelliJ version etc matrix, rather than post new comments on them.
• Make the issue title throwable.toString().
• Better stack trace matching to stop the same bug producing multiple issues. We have to be careful here not to lose important information. There are a few options:
  • Post a new comment for each new stack trace.
  • Create a gist and add the stack traces to there.
  • Create a graph of possible call paths.
• Reopen closed issues when the mcdev version is greater than the latest mcdev version stated in the issue.
• It would also be nice to have an automated way to clean up existing issues.
