Zap 0.7.0 Beta

## Release notes This release contains several new features including support for lnd v0.10, keysend, multi part payment, payment probes, Tor and more. As usual, this release also contains a number of optimisations and bug fixes. ## LND 0.10 We now ship with [LND 0.10.2-beta](https://github.com/lightningnetwork/lnd/releases/tag/v0.10.2-beta) which delivers many improvements and enhancements. We continue to support connecting to external LND nodes that are running prior versions of LND, though we encourage all users to update their nodes. ## Payment Probes We now use payment probes to get an accurate fee estimate prior to making a lightning payment. This is done by sending a payment with an unknown payment hash and inspecting the returned failure. If it originates from the final destination, the route is deemed to be valid. Following through with the real payment after a successful probe is very likely to succeed and by using the route returned from the probe we can be sure of the exact route and associated fees that will be used. ## Multi Part Payments (MPP) If we are unable to send your payment using a single route we will try to leverage MPP - splitting the payment over multiple parts - in order to improve chances of delivery. ## Spontaneous Payments (keysend) We now support keysend payments. This lets you send Lightning payments without the need for the recipient to provide you with a bolt11 invoice first. All you need is the pubkey of the node you want to send to. Using keysend you can send any amount of sats, any number of times to the same address (within your channel limits). The node pubkey acts like like a static reusable receive address. ## gRPC over Tor In this release, we have added support for connecting to your LND node's gRPC interface over [Tor](https://www.torproject.org/) (via a `.onion` address) which enables you to connect to and control your node without exposing it to the internet. ## LNURL Channel As part of our continued rollout of the [LNURL protocol](https://github.com/btcontract/lnurl-rfc) we've added support for [`lnurl-channel`](https://github.com/btcontract/lnurl-rfc/blob/master/lnurl-channel.md) which makes it possible to use services like [LNBIG](https://lnbig.com/) or [Bitrefill's Thor](https://www.bitrefill.com/thor) to request inbound liquidity without worrying about manually opening channels. This adds to our existing support for [`lnurl-withdraw`](https://github.com/btcontract/lnurl-rfc/blob/master/lnurl-withdraw.md) which enables you to quickly and easily withdraw funds to your wallet without needing to create an invoice. ## Hold Invoices Hodl Invoices allow you to have manual control over the invoice settlement process - once payment has been received you can choose to accept or cancel back the payment. ### Bug Fixes * **app:** ensure app restarts during autoupdate ([8346450](https://github.com/LN-Zap/zap-desktop/commit/834645025cb83e95ed3de5c04076d6cf534bb5c6)), closes
