[dev] Horde 3.2 release series: remove PHP 5 code?

[Chuck Hagenbuch]

Horde users/developers-

I tentatively propose that once Horde 3.2 is branched, we remove the  
PHP 5 libraries from the FW_3 framework. Horde 3.2 maintains PHP 4  
compatibility, and these libraries will continue to evolve with Horde  
4, so I don't see an advantage to including them; they'll just cause  
people to have old versions that might not be BC with the Horde 4  
release (and in some cases certainly won't be).

I'm open to arguments that it'd be better to include them, though.  
What do people think?
