ErisDS 6dd753212f Show message and don't start on unsupported node versions
closes #292
- added engines and enginestrict properties to package.json
- these provide warnings / errors when installing through npm
- added our own check using this info on start, throws a useful error and stops the app if the node version is not supported
- also switched sqlite3 to the latest version and checked it works with various node versions
