Fix quickutil dependency order.

Apparently, it's not possible to use :import-from as a forward declaration, so
the file automatically generated by quickutil neeeds to be loaded early.

	* src/util/quick.lisp: Rename to quickutil.lisp.
	* com.dvlsoft.declt.asd (generate-quickutils): Update accordingly.
	(:com.dvlsoft.declt): Depend on quickutil.lisp before package.lisp.
