lncli: live table-based payment updates
Level up the cli user-experience by presenting a nice table instead of a stream of long intermediate payment state json.

![lncli-live](https://user-images.githubusercontent.com/4638168/79354331-930ba280-7f3c-11ea-9d23-194f6e2dc83d.gif)



bhandras: This is really cool. 
joostjager: Added commit that shows node aliases instead of (truncated) pubkeys
Roasbeef: Committed as `6ffdf7ef1fa080844af9fced3a57e54d0ee22729`. 
joostjager: Removed `uilive` dependency which broke the build on illumos and solaris. Turned out to be very easy to rewrite the terminal.
joostjager: Tacked on commit to rename the mpp parameter to `max_parts`, to align with the P in mPp.
joostjager: Lightning-rfc also consistently refers to it as `multi-part payments`

https://github.com/lightningnetwork/lightning-rfc/blob/master/04-onion-routing.md#basic-multi-part-payments
joostjager: Todo: test on windows
joostjager: Windows failed the escape sequence test, forced json.
