[rules-users] Declaring events separately from rules breaks expires

[Edson Tirelli]

   Samuli,

   Are you adding your event declaration file before the rules that
use them? As of today, you must always do that, but as long as you do,
it should work even if they are in separate files.

   Regarding the update, it is not possible to do that today, but feel
free to open a JIRA. I think it is something we should do.
