fix bugs #211, #216, #217, #222 and bump to 0.4.2

- extract.py: use str(path) for node IDs to prevent same-basename collision (#211)
- build.py: normalize from/to edge keys before KeyError (#216)
- export.py: guard ZeroDivisionError when graph has no edges (#217)
- hooks.py: remove stale CODE_EXTS filter, rebuild on any changed file (#222)
