[development] Rules action to impersonate a user

[Christian López Espínola]

Haven't tested your code, but maybe you want to take a look at
masquerade_switch_user
and masquerade_switch_back:
http://drupalcode.org/project/masquerade.git/blob/HEAD:/masquerade.module.

And if the impersonation is only for the given request, maybe just

 global $user;
 $previous = $user;
 $user = user_load($uid);
// Do your stuff.
 $user = $previous;

would work.
