Rename profile's hook_install() to hook_profile_install() to avoid namespace conflicts

Should profile's hook_install() be renamed to hook_profile_install() to avoide namespace conflicts if somebody has a blog.profile? Of course they can always name it blog_profile.profile or something, but IMO it'd be nice to differentiate from a module's install hook as they are a bit different and it's sorta confusing that a profile will install a bunch of modules which in turn run the module's install hook, then our profile's install hook will be fired.

So I propose renaming this to hook_profile_install() for D6.

I updated the install profile docs at http://drupal.org/node/67921.
