Modern AE2 Additions

The long awaited 2.0 release. Major changes include (see previous changelogs for details):

 - New backend for multi p2ps, used to make rf and eu p2ps much more efficient

 - New nerf option for EU p2ps, making them more like GT cables and giving a soft cap to how much they can transfer

 - Pattern p2p refactor, making them less janky internally (meaning they should play nicer with other mods) and adding some polish to them (better naming in pattern terminal, allow nested p2ps, other stuff probably)

For this update specifically, the changes are:

 - fix a crash for input single EU p2ps without a grid node

• fixes a crash with EU p2ps
• fixes multi pattern p2ps not reverse tunnel to multipart providers
• fixes a NPE with single pattern p2ps
• Potentially fixes an issue with reverse tunneling pattern p2ps and GT machines

• Implemented a new optional nerf for EU p2ps

• Migrates old pattern p2ps to the new system

• Fixes a crash with pattern p2ps outputting to non-machine blocks
• Multi pattern p2ps now automatically refresh their pattern inputs
• Part names aren't copied with multi p2ps, allowing them to be named easier
