Assets - Add bock asset features to compile dependencies and version - WIP

[jesseeproductions]

Adds methods to set dependencies and version based on complied block assets.

Utilize the following methods when adding an asset:
Set path automatically:

Asset::add(
	'event-schedule-manager-speaker-list-block-js',
	'js/app/speaker-list/index.js'
	)
	->set_as_compiled()
	->add_to_group( 'event-schedule-manager-editor' )
	->register();

Or set the path manually:

Asset::add(
	'event-schedule-manager-speaker-list-block-js',
	'speaker-list-block-index.js'
	)
	->set_as_compiled()
        ->set_compiled_path( 'js/app/speaker-list/index' )
	->add_to_group( 'event-schedule-manager-editor' )
	->register();

Both examples assume the default asset path is in src/resources/

I would love to see us simplify to allow assets to be compiled or not and then just add the compiled variables to the ones that we have set.

• I updated the coding to have set_compiled_data() method that can be used to setup the asset to use the compiled data if found.
• I did pass the src to it because the slug would have to be changed to the src and gives you less options in naming.
• The get_version and get_dependencies are updated to use compiled data if found.

I'm closing this one in favor of a further evolution in #19
