Update inara plugin to use incremental shiplocker updates when sending info (and send backpack, if possible on INARAs side)

[A-UNDERSCORE-D]

Currently we:
1. Only send ship locker info, backpacks arent included
2. Only send FULL ship locker info, transfers are not included

For 1, we're waiting on a response from artie about if we should, if so...
1. We need to track what we've sent to artie and remove stuff from the backpack if the player dies (or assume the next ShipLocker will get it
2. implement additional backpack endpoints if those become a thing

Update from artie, dont do this until some time in the future if backpack specific support is added

for 2, if transfers are working correctly we should send them to incrementally update inara

[14:19] Artie : yeah, better to keep it shiplocker-only for now. Less problem for everybody :slight_smile:
[14:20] Artie : in the Inara API events, everything is presumed to be in a shiplocker and it may be extended for the backpack in the future (by allowing another value in the itemLocation property)
