ide instructions in readme

The readme instructions don't mention enabling annotation processing in your ide, and even after doing so my code compiles but intellij 13 CE (OSX) cannot find the generated classes, making the editor show compiler errors.

These instructions for eclipse look promising, but also a pain to have to set up manually.

Btw I'm glad to have an alternative to lombok! I like the feature set but we've been plagued with compatibility issues with new ide/java/lombok versions.
