Title: Update the directory entry writes to use STORE

This patch will break the JarBuilderTest, but I already fixed that in my other branch zundel/super-shady-jar-tool. It saved 20 CPU seconds in building a large jar file (190MB) and all of that translated into real time savings. FYI, I did not run these numbers multiple times so treat them with suspicion.
