Support for custom Electrum server (#739)

Browse source 
We can now use the `overrideDefaults` parameter in `Setup` to programmatically 
provide a custom electrum address when starting eclair, by setting the 
`eclair.electrum.host` and `eclair.electrum.port` entries in the configuration.

When these entries are set, eclair-core will always try to connect to this server
instead of relying on a random server picked from the preset lists.
