Subject: feat(gs/emacs): Generate org agenda commands from project tags

Auto-generate org agenda commands from project tags of the form
`project__foo_bar`, prefixed with `p` and named based on the first
letters of the words in the project. there is (obviously) some overlap
here but that can be fixed by just adding extra underscores to things to
disambiguate.
