Make the distribution layout more clear

[lfryc]

I would like to make the layout of ZIP distribution as clear as possible.

Currently, JAR artifacts are distributed in ZIP distribution as follows:

/artifacts
   /archetypes
   /framework
       richfaces.jar
       richfaces-sources.jar
   /lib
       {dependency}.jar
/examples

I propose to change this layout for several reasons:

* layout should be understandable to newcomers

** word artifact is rather familiar to Maven users

** word framework doesn't have to be taken well

* I assume others projects more or less follow one of following "conventions"

----

This layout counts with richfaces.jar in top-level directory:

/archetypes
/examples
/lib
    {dependency}.jar
richfaces.jar
richfaces-sources.jar

or the one which has /bin directory with richfaces.jar:

/archetypes
/examples
/lib
    {dependency}.jar
/bin
    richfaces.jar
    richfaces-sources.jar

I would also like to bundle a richfaces-source.zip distribution which would contains packed contents of Maven repository.
