Add a framework for linting projects

Currently comes with just an absolute path linter, as well as a relative path linter.
There is a bug in roxygen migration that results in the deletion of hand
edited Rd files. I believe the bug was fixed but perhaps not on CRAN yet?
(or perhaps this is another manifestation of the bug). If you just restore
the deleted Rd files and make sure they don't have the auto-generated
header then they should get preserved in future runs (they only get deleted
during the migration step)
