ports-mgmt/portfmt: Update to latest commit
- Extend data model to allow for target command formatting if turned on with the new -t flag
- General parser improvements
- Sort USE_PYQT like USE_QT
- Add preliminary support for WIP USES=cabal options helpers/variables
- Add a portedit command which instead of formatting the entire file only formats edited portions of it. As a proof of concept this for now only has a 'bump-revision' command to bump PORTREVISION of a port, and a 'get' command to return unevaluated variable values as parsed by portfmt.
