Added cmake rules for installing tools in bin dir

When performing the tutorials, I wanted to use the
tools/xmlGenerator/hostDomainGenerator.sh script.

In order to do that, i had to copy manually my scripts files
to the pfwInstalledDir/bin directory.
This patchs completes the install target by copying the needed files

XmlValidator tool

This tool can be used to validate a set of xml files against w3c
schemas.

It scans a directory recursively and checks for .xml files in it.
For each file, it extracts the current schema file based on a convention
(the corresponding schema file must have the same name as the root node)
which is used in the parameter-framework.
