Uniformize context for onBlock callback

* when opts.fadeIn > 0, onBlock callback context is lyr3
* when opts.fadeIn == 0, onBlock callback context is this

--> with this patch, when opts.fadeIn == 0, onBlock callback context is lyr3
FIX #36
add blockCounting option. If this option is true, multiple block calls are possible. This option does not work with "timeout" option, and is meaningless with "ignoreIfBlocked" option.
add composer component package
