* XEM is using 1.5 since we it's going to be released soon and it'll be released with 1.5

* I haven't touched Curriki since I'd prefer if David manages the curriki build since I don't fully control curriki's build process (there are some other scripts) and since Curriki development is critical and cannot fail. Note for David: when the disk is full on the maven.xwiki.org machine, we'll need to make up some space by cleaning up the SNAPSHOT repository and thus 1.5-SNAPSHOT will disappear at that time, causing a build failure if Curriki's modules are not updated to use 1.5 or 1.6-SNAPSHOT. Also note that for XEM and XE I have introduced a property to manage the Tools version in a single place.
