Improvements for OpenChannel screen

[Darth-Coin]

I would like to suggest an improvement in the opening channel screen dialog.

• "amount satoshi" - to have visible the available balance to open a channel
• also a simple button/option to check "use all balance" to open a channel and deduct the fees (idiot proof)
• "fee rate" - when is in auto, user can't see how much is in reality. Add a visible rate, like when you slide the button. Or add option to put it manually. or maybe user just want to spend a specific amount in sats and from there UI will calculate it how much is in sat/vB (maybe user is dumb and don't know what is sat/vB). or like in Thunderhub showing total sats fee, when you put 1 sat/vB, so user will see exactly the total cost.

This is pending a fix for lnd before we can do this. lightningnetwork/lnd#4029
