Ability to filter issues with certain labels from the release notes

[arhohuttunen]

Currently, if you want to close an issue without implementing anything, there's no way to exclude it from the release notes. This could happen if you just want to resolve an issue as not a bug, non reproducible, not going to implement, etc.

The only way to do this seems to be to delete the issue, which will of course not retain any information about the issue.

One possible solution would be to add the ability to filter issues marked with a certain label from the results.
