new tool: rpmguard - print important differences between RPMs

[Kamil Paral <kparal redhat com>]

Hi,

I have created a simple tool called rpmguard for checking differences 
between RPM packages. It is very similar to rpmdiff, but it prints only
important changes, not all. Therefore it can be used every time a new 
package is built to easily see if something hasn’t went completely wrong.
