[Yanel-dev] new build property "local.config.home" supplementing "local.config.dir"

[Guillaume Déflache]

Hi!

This property allows to store all the local Yanel configuration in a 
directory *not relative" to $YANEL_HOME/conf/ (see 
http://svn.wyona.org/repos/public/yanel/trunk/src/build/build.properties 
for more info).
(Fortunately entropy did not grow too much since I also removed a 
similar but yet unused property there! ;) )
This helps a bit for Hudson projects where it can then be stored out of 
the workspace, thus avoiding a complete wipeout on failed svn updates.

Originally I wanted to support relative paths in Yanel conffiles to make 
it mostly configuration-independant, but it proved much harder than 
expected (some refactoring of the build process of the resources and 
realms would be needed, and Michi is also doing some ATM, so I'd better 
wait).
Anyway I'll try to get there slowly on my free time eventually...

Cheers,
    Guillaume
