* chore: fix lint warnings
* chore: another try at python import errors
Looks like the problem is that dbus_mock.py is running as

module. Moving it up into the `script/` directory seems to
solve the issue.
* Enable easy rebuild of native modules for unreleased electron
Sometimes when developing locally (as I found this morning) you want to rebuild native modules
against an unreleased version of Electron (in this case local master). This PR adds a simple
script to launch a local HTTP server that generates and hosts the required header and checksum
files to rebuild modules. So far only tested on macOS but should work on all OS's
* Allow custom port
* clean up serve script
* make optionality more obvious
