* plugins/layout: Log script errors at warning level rather than verbose level. * microtouch.lay, pntnpuzl.lay: Improved pointer mapping code. * Reordered all layouts to place views after element and group definitions and scripts last. This matches how layout files are interpreted by MAME. * Fixed various errors identified by validating layout files against an XSD schema.
