Enhanced Periphery

Adds some quality-of-life features to CC: Tweaked peripherals.

New functionality:

• listWithCapabilities(): Same as list(), but adds hasEnergy, hasFluid, hasInventory if the item supports those capabilities.
• getItemInventory(slot): Retrieves the inventory of a specified slot's item, in listWithCapabilities format.
• getItemInventoryDeep(slot): Same as getItemInventory, but recursively lists nested inventories.

Enhanced functionality:

• getItemDetail() returns energy and tanks keys for stored FE and fluids, as applicable.
