- Adds the auto-minor-mode package to replace our in-house
implementation.
- Merges associate! into the def-project-mode! macro because associate!
on its own is less useful than auto-minor-mode-alist,
auto-minor-mode-magic-alist or hooks.
- Changes the semantics of :modes and :add-hooks properties of
def-project-mode!. Its arguments are evaluated as is; lists will need
to be quoted.
