[Yanel-dev] build.properties.version introduced

[Michael Wechner]

Hi

I have introduced a build.properties.version (similar to the version 
number of realms.xml and resource-types.xml), because
I had very strange problems during startup and the reason was, that my 
local.build.properties didn't have zhe same configuration
re ambiguous xerces libs and hence I had the wrong xerces and it took me 
quite some time to figure this out.

So the build process will compare the version numbers of 
local.build.properties and build.properties and if these are different will
throw an exception and tell people to "synchronize" these two files.

Thanks

Michael
