Re-write start_ln such that we can create up to 10 nodes locally for testing. Useful for scenarios where more than two nodes are needed Changelog-Changed: contrib: startup_regtest.sh `startup_ln` now takes a number of nodes to create as a parameter

## Short script to startup some local nodes with
|
|
## bitcoind, all running on regtest
|
|
## Makes it easier to test things out, by hand.
|
|
|
|
## Should be called by source since it sets aliases
|
|
##
|
|
## First load this file up.
|

|

|
|
##
|
|
## $ start_ln 3
|
|
##
|
|
## Let's connect the nodes.
