Revision 775456

Fix issue Felix-1159
Add a 'version' attribute to component type and instances allowing to select the component type version when an instance is declared.
<component classname="..." version="1.0"/>
<component classname="..." version="1.1"/>
<instance component="..." version="1.0"/> -> Use the version 1.0
<instance component="..." version="1.1"/> -> Use the version 1.1
<instance component="..."/> -> Any version

This commit also define the "bundle" constant reusing the bundle version:
<component classname="..." version="bundle"/> -> Use the bundle version

The API also supports the version API, add a getVersion method in the ComponentTypeDescription and in the Factory interface.
