first shot at permissions
permissions associations basically work. likely plenty of bugs. need to write tests.
passes tests for permission, task, user models
all the tests pass! think I even fixed some old bugs.

now, to actually implement the permissions...
added flash to user list (for deleting users, e.g.)
first tests for permission creation/destruction (with AJAX)
further tests for permission controller
further tests for permission, now passing.
properly handles permission/task/user deletion.
added index in permissions on user & task.
added more indices that I should have added last time
permission controller tests passing.

placeholders for views/permissions/create|destroy
first pass at permission UI working, on task menu. still need to have response handled.
permission creation/destruction response handled.
next up: changing permissions.
permission updating basically done.
next up: feedback on permission CRUD failure.
feedback working for update failure. Need to do creation and destruction.

Should just need to figure out AJAX response from create/destroy button.
feedback good for creation and destruction.
caught and fixed bug with changing last permission away from owner; can no longer orphan tasks that way.
