Ultimate Kernel Cleaning Script - 2.0 [UPDATED ON 20110713]

Since many users have complained about phone instability after flashing another kernel, I decided to make a Recovery Script to clean everything may cause instability.
As we know also zach made something like this, but his script deletes only init.d config files while many problems are generated by cache and dalvik-cache waste files.

So here I am with the Ultimate Kernel Cleaning Script.

With this new 2.0 I've included some features taken from the awsome modded CWM made by Vorbeth, so thank him

HOW TO:
- Place the zip file in your internal SDCARD
- Flash it as a normal package from ClockworkMOD recovery
- Flash any kernel (zach's, tkglitch's or bilboa's)
- Reboot

Everytime you need to change/re-flash a kernel, just apply this before
