This also renames Reminder Interval section into Reminder Settings and changes names of corresponding classes and files.

Thank you very much for the pull request. The limit number of repeats feature has been requested many times so users should be happy with it. I'll try to find a time to review, merge and test pull request and release new version in the next week.

Thanks. I have another feature in the pipeline coming after this, but not sure how to add it to a separate pull request... if I push it to master it gets automatically added to this, so I've pushed it into another branch. Once this is merged, I'll push it to master and create another pull request.

The feature is about creating a dismiss notification whenever the reminder is active. When enabled, it allows users to disable reminders without dismissing the original notification. Here is diff if you are curious: https://github.com/rryk/MissedNotificationsReminder/compare/master...dismiss.
