fftw name in Fedora Extras

Hi,
	this message is intend to warn people using Fedora Extras that fftw will 
refer to version 3 (actually version 3.1 recently released), and a new 
package called fftw2 will take place of version 2.

	This change should only matter if you maintain rpm packages, for users yum 
should take care of the upgrade path. :-)

	This change will take place in the next couple of days.

	Best regards,
