I've made a couple changes to openssl so test grimoire on the server 
should be good and all working.  If anybody has any concerns about this 
kind of trigger, please speak up. :)

Any change from 0.9.7x to 0.9.8x (or any other change like that, like 
for example backwards) should trigger an automatic recast of all the 
spells necessary after openssl itself compiles.
