Use effects gratings with SD-Card ILDA files with Proline Series lasers

Some of the Laserworld Proline Series lasers have a built-in SD-card playback system. 
The ILDA files can be given certain attributions in the .prg file, that acts like a library for the playback system.

Example:

File1.ild,12,3,0

Means: filename, scanspeed, repetition rate, grating effect

The grating effect specified with the last parameter (1,2,3,...) is applied to the ILDA frame.
