Wagn 1.5+3+upgrade notes

If you've been encountering caching problems, such as seeing old content that you thought you had edited, we've added a URL to clear the cache. See administration.

Search cards are now 10 lines tall instead of three, so you have more space to see and compose WQL.

+*options cards can now be Pointers (before they could only be Searches). We've changed the default on new +*options cards to Pointer, as those are accessible to more people, but you can always change it to Search if desired.

We've added a URL views.
