 * @plugindesc Insecure method of obtaining DLC information, but it works.
 * @author Anton Uklein
 * *
 * @help Remember to have a DLC folder in your game directory to make this work!
 *
 * Please note that this is supposed to be an internal plugin, so it has
 * almost no error correction involved in any way,
 * and your project might break if called improperly.
 *
 *
 * Call a Script DLC_Check() to check for all the variables in the array
 * dlc_filenames.
 * If you call it this way, it checks for ALL the files at once
 * and flips switches in the order the files are detected, starting at 100.
 *
 * Alternatively, you can call a Script
 * DLC_CheckS(filename, switchValue),
 * which will look for a file with the name that's
 * the same as filename, and set the switch at switchValue
 * to true or false, depending on whether or not it's found.
 *
 * Note that filenames do not have to end in .txt and
 * switchValue begins with a 1, not a 0.
 *
 * @param dlc_filenames
 * @type Text[]
 * @text DLC
 * @desc Load your dlc filenames here!
 * @default ["debug.txt"]
 *
