drush command for rebuilding permissions and roles

Alright, this ought to do it! There are two commands (I documented them well with help and argument descriptions).

- drush rebuild-perms
- drush sec-perms

The former is a straightforward call to the permissions rebuilding function in the main module. However, while writing this I realised it fails silently if Secure Permissions is deactivated, so I decided to check for that and fire an error if someone rebuilds perms without having the module active.

I then thought "if that happens to me, I want to be able to activate it from terminal!" so I wrote the latter command. At the moment all it does is activate/deactive the module by setting the secure_permissions_active variable, however I've made the function nice and generic in name and nature, so anyone could extend it in the future to allow further settings manipulation from drush very easily.

This is tested against Drupal 6 but not Drupal 7, though as far as I can tell from the module code it should also work for Drupal 7. Please test and report back - of particular concern is whether the sec-perms on/off commands work in D7, because there is a subtle difference in variable value (from 1 to TRUE and 0 to FALSE). Should still be ok, thanks for PHP not being too fussy about type, but I haven't tried it.

That's all folks! I've tested it and it works for me.

Oops - forgot a help entry for drush sec-perms. New patch.

My colleagues have reviewed it (we're using it on production servers). Don't know if that's good enough for R&TBC. Really I shouldn't 'self-review', but I promise it works!

We definitely have an interest in the continued maintenance of this module, so I guess that's a yes! If you need someone to cruise the issue queues with you then we'd happily do a bit of that... Not sure how much active dev we'd do, but then we did this, so I guess there will be things that come up that we would add as we find them.

Oh, I need to do something with this then! Bumping it for my attention.

Committed to Drupal 6 version. Needs porting to Drupal 7.
