Chart component

chart component moved to framework
bridge created

There are some changes to be done, I am aware of:
- change prefix s(sandbox) in comments to r
- some files do not include the licence, should it be placed in all files?
- I've made changes to resources in https://github.com/Lukindo/richfaces/blob/master/framework/src/main/java/org/richfaces/ui/output/chart/chart.template.xml
I commented out some files. They should be probably removed but I was not sure.
    - What file is necessary to use rf.ajax call?
    - Is jquery.js included automatically or should I list dependency explictly?
