yet another try at energy issues

fix requesters not being added to the energy grid


partially revert the energy 'fixes'


potential desync on item count


energy and items change

CHANGES.md

@@ -15,6 +15,10 @@ Fixes:
  - Exclusive Blocking mode for GTCE ( shapes, molds and configured circuits do not block GTCE machines )
  - Blocking modes default to block on any item in the iventory the entity exposes
  - Fuzzy includes items that report that they're damageable, but report a maxDamage of 0 ( auto-crafting of basic capacitors -> resonant capacitors is now possible ) <- Broken item implementation.
+ - Fix CME exceptions on the energy grid
+ - Fix AE going offline even with enough power by extracting from the local buffer always last
+ - Fix IO-Port copying craftable flag into items
+ - Fix NBT of old items not clearing on drives that reached 64 types once

  - Count items set in interfaces before queuing crafting for them needlessly
  - Backported b7ca98d ( Avoid copying items on simulated item extraction )
  - Cache some level emitters functions
+ - Reduced import bus insert simulation to 1 before real insertion (if possible)
+ - Backported itemlist re-implementation along with pattern changes to avoid CraftingManager fallback issues
+ - Instead of recalculating all the content of the network on every change, track the changes properly and apply them to the cached list of items

  - Added bar on the interface terminal that search by inputs ( The one on the LEFT, also searchs by interface name )

  - Patterns can now be made with items currently showing on JEI. ( This is overriden by Just Enough Energistics. )
  - Added multiplier buttons to processing pattern gui

  - Encoded patterns can be draggred on the interface terminal.

-  -JEI auto switches between crafting and processing patterns
+ - JEI auto switches between crafting and processing patterns
+ - GTCE Blocking mode work through phantom itemfaces
+ - Shift-clicking blank patterns into the pattern terminal will try to fill the blank pattern slots first
+ - Mismached simulated/real item count ( most often due to compacting drawers ) will now tell the player wich item cause the failure when trying to start a craft
+ - Added 'pattern expansion' cards that adds an extra row of patterns to interfaces. up to 3 card on an interface. (each card will increase the interface idle power draw by 4 times)
