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
