core, XEP-0315: move XML element handling to sat_tmp: XML Element is now implemented in sat_tmp, so it can be available also for SàT Pubsub. The XEP-0315 is thus not needed anymore and have been removed, XEP-0315 namespace has been added to base disco features. Use the new install() function of sat_tmp to do the patching.

You'll find install instructions on the following link: http://wiki.goffi.org/wiki/Salut_%C3%A0_Toi
