Robot dupes ic2 seed bags

[repo-alt]

Illustrations here:
GTNewHorizons/GT-New-Horizons-Modpack#5657

The reason is that ic2 crop seed onItemUse tries to set
entityplayer.inventory.mainInventory[entityplayer.inventory.currentItem] = null;
but for the robot entityplayer.inventory.currentItem is not set (probably due to tool belt/main inventory distinction)

I understand that direct access to the player inventory is not a good idea on ic2 side but it is somehow unlikely that they will fix it, so, do you have any idea how to circumvent it on OC side? Because all I can think of is another hack in li.cil.oc.server.agent.Player.activateBlockOrUseItem

i've had to fix numerous very difficult inventory issues due to ic2 before.
i see in your ref'd ticket some code and screenshots. when i get around to testing your PR i'll also poke at this

Thanks. Yes I saw a workaround for ic2 tools there.

There is one more bug with exactly same cause - when applying ic2 crop tile to an empty crop tile (for cross breeding), the stack of 1 crop cannot be applied, because it crashes trying to set
player.inventory.mainInventory[player.inventory.currentItem] = null;
where player.inventory.currentItem is -1 because it is from equipment inventory.
(In general the trick with setting player.inventory.currentItem to -1 for equipment slot looks rather fragile (unfortunately I cannot suggest better alternative for 1.7.10))

The best solution would be to write an inventory proxy which combines two inventories (mainInventory and equipmentInventory), then rewrite agent.Player to use that.
