Build Dashboard
* Feature: Added the option to send a different kill signal for each swamp service
* Feature: Added the option to set a `mode` for the swamp (`local` or `remote`)
* Feature: Prompt the user when trying to perform dashboard actions when swamp runs in `remote` mode (stop, start or restart service)
* Dashboard: Some design changes as (antonzy)[https://github.com/antonzy] asked :)
