bluez-utils is 3.7-2.2

After hours of searching on the web, I found out that bluez-utils 3.7 doesn't support Dell bluetooth. Version 4.5 does, but I couldn't find the source for it. So I cut the code from 4.66 on CentOS 6, and patched the 3.7 version.

Here is the patch:

I have recently wiped my system and loaded CentOS 6.2. Blue tooth works much better in this version. Can actually use blue tooth devices in Linux now.
