[ticket/11458] Search for permission language files in extensions

Extensions that add new permission masks only need to add a permission file in
the language folder of the extension. The file must start with 'permissions_'
eg 'permissions_blog.php'. The permission language file will be automatically
included when viewing/setting permissions.

[ticket/11458] Add functional test

Since there is no test method to include extension language files, a
functional test seems more appropriate.
We add a permission mask 'acl_u_foo' with translation found in extenion
'bar' and confirm that the permission language file 'permissions_foo.php'
from 'bar' was added by asserting that 'Can view foo' exists when viewing
user permissions in acp
