MC1.21.x-4.2.0-TTE

• squadron contacts
• carrierless squadrons
• tweaks and patches here and there
• properly react to craft type load events
• respect the size of skiffs too when forming up

MC1.21.x-4.0.0-TTE

Depends on TTE Movecraft!

New features:

• squadrons merge back to crafts they would merge with on release
• switch to gradle
• use datatags for carrier storage internally
• all signs use the new sign system
• control individual squadron crafts with shift clicking signs and having the control item in the off-hand for that one
• improve positioning collision a little bit (it does it now craft by craft, not all at once)
