Unify naming of wallet actions (e.g. sending / receiving / paying an invoice / deposit / withdraw)

[klochowicz]

I think this discussion can wait until after the tournament; for completion here are some of my thoughts. We don't have to action this now from my point if view :)

I think pay makes sense in the context of an invoice, but is this not in conflict with our discussion about send / receive vs deposit / withdraw? One conclusion there was that we could agree on send/receive and send-on-chain/receive-on-chain. Would you keep the actions buttons for the Lightning wallet as Send and Receive but use pay in the context of an invoice?
