Use initZygote instead of loadPackageParam

loadPackageParam is called for each package, so the method is probably being hooked each time a package is loaded, which is a huge waste.

This patch uses initZygote which means the method is hooked once and applies everywhere.

Please test it before merging, this project seems to have been done with Android Studio, which means it's messed up in Eclipse and eclipse can't build it :)
