Release v0.4.0

Changed default log level to debug and adapter repo to beta (#74)
Added verification of .npmignore and .gitignore (#46)
Restarting adapter with watch when adapter config changes (#47)
Running "npm run build" before installing the adapter (#77)
Fixed bug that "watch" wasn't syncing files upon start-up, but only when they changed (this was causing issues with sourcemaps).
Added --noStart option to watch, this allows to start the adapter from an IDE afterwards
