added sample
Merge branch 'master' of https://github.com/danjee/wicket-bootstrap.git
Added improved javadoc
Added chained constructors
Added default values in configuration
Also an ugly workaround in default keys max, min and step

I think a modification has to be made in jquery-selector AbstractConfig
so the use of 

private static final IKey<? extends Number> max = newKey("max",100);

will be valid
remove white lines
import resources with eclipse 'Save actions' disabled
