Scripty: conversion of kdelibs and kdebase done

[Nicolas Goutte]

I have finished to convert the kdelibs and kdebase KDE4 modules to use the 
Messages.sh scripts instead of the "messages" targets of Makefile.am files.

The Makefile.am are unmodified for now, so that you can (counter-)check the 
changes.

I have also added a I18N section to the porting file:
trunk/KDE/kdelibs/KDE4PORTING.html

I have made Scripty independent of the Makefile.am.in and Makefile.am files, 
so it should continue to work if the KDE build system is changed for kdelibs 
and kdebase.

Note: the Messages.sh scripts can work for all KDE4 modules. You can mix 
"messages" targets and Messages.sh scripts in one module. (Of course, not in 
the same directory. In that case, the Messages.sh script has the priority.)

Have a nice day!
