item cost review

fix job byte size to 8 per crafting + 1 per item used/stored

CHANGES.md

@@ -15,10 +15,6 @@ 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

  - Patterns can now be made with items currently showing on JEI. ( This is overriden by Just Enough Energistics. )

- - 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
