Overhauled Mapbase's GitHub-specific files to be more effective and project-agnostic
* Moved CONTRIBUTING to .github so it can be recognized as contribution guidelines
* Added more issue templates and made them more project-agnostic for forks
* Renamed issue templates so "Bug report", "Feature request", etc. come first when looking for the right template
* Added pull request template
