Improve MSW export including multi lateral wells

Based on branch https://github.com/OPM/ResInsight/tree/system-msw-refactor

- Move completion settings to property of well path
- Rename to RimFishbones
- Export implicit COMPSEGS for fishbones main bore
- Add valve for each branch
- Increase version number to be able to handle import of legacy project files
