Support dir nesting (and further minor tweaks)

[voydz]

Hi there, as issue #8 mentions, currently there is a problem with this package, if your language directory contains subdirs.

This pull requests should fix this issue. All unit tests remained green for me. Furthermore there are some additional tweaks, namely:

• Removed the dependency on laravel/framework and added illuminate/console, illuminate/support respectively (also supporting versions 5.2 and 5.3)
• Merging the scaffold config of this component into the runtime application config as a default, as those values are fine in most cases (removing the need to publish configs)

greetings voydz
