Decoupling and generalization of templates

Improvement for factions and templates which will allow decoupling of the templates from the actual units
- Implement UnitGroup class which matches unit_types and possible templates as the needed abstraction layer for decoupling.
- Refactor UnitType, Add ShipUnitType and all ships we currently use
- Remove serialized template.json and migrated to multiple yaml templates (one for each template) and multiple .miz
- Reorganized a lot of templates and started with generalization of many types (AAA, Flak, SHORAD, Navy)
- Fixed a lot of bugs from the previous reworks (group name generation, strike targets...)
- Reorganized the faction file completly. removed redundant lists, added presets for complex groups / families of units like sams
- Reworked the building template handling. Some templates are unused like "village"
- Reworked how groups from templates can be merged again for the dcs group creation (e.g. the skynet plugin requires them to be in the same group)
- Allow to define alternative tasks
