[rules-dev] Drools syntax diagrams - redrawn

[Edson Tirelli]

   I agree with Wolfgang here in the sense that it is much better a
low level, not so friendly, ****up-to-date**** diagram, than the
higher level, manually drawn diagrams that we end up never having the
time to update...

   Just my 0.02c.

PS: but I would prefer deprecating pre-fixed or/and instead of
infix... hehehehe
