Move to loading migrations using loadMigrationsFrom instead of publishing

[chrispelzer]

Implement the option to have the migrations utilize Laravels loadMigrationsFrom without the need to publish the migrations.

Renamed the migration to work with both loadMigrationsFrom and publishing, publishing required the date/time to be part of the file to be consistent and not have new migrations, loadMigrationsFrom the date/time doesn't matter.
