 *  - This plugin is released under the zlib License.
 * 
 * This plugin allows characters to emit step sounds when walking.
 * 
 * How to Setup a Step Sound:
 * 
 * The first step are set the Step Sound Settings in this plugin
 * parameters. The definitions are simple, but pay attention to the 
 * base name of the SE file and it's variations number. The plugin 
 * runs the SEs randomly within the maximum number of variations.
 * Works as follows:
 *   | Base Name + Random value within the amount of variations
 * Examples:
 *   | Step Sound Setting: 
 *       | Base Name: Step_Dirt
 *       | Variance: 4
 *   | This setting may randomly call the following files:
 *       | Step_Dirt1
 *       | Step_Dirt2
 *       | Step_Dirt3
 *       | Step_Dirt4
 * 
 * After that, you can add a step sound setting in the tileset 
 * terrains or in the map regions.
 * 
 * In both cases the definition is made through the same note.
 * 
 * Tileset Note Tag:
 *   <stepSound terrainId: stepSoundId>
 *       | This note tag add the specific step sound to the
 *       | specific terrain.
 * Usage Example:
 *   <stepSound 5: 1> 
 *       | This tag adds the step sound of ID 1 at the tileset
 *       | terrain 5.
 * 
 * Map Note Tag:
 *   <stepSound regionId: stepSoundId>
 *       | This note tag add the specific step sound to the
 *       | specific map region.
 * Usage Example:
 *   <stepSound 3: 4> 
 *       | This tag adds the step sound of ID 4 at the map
 *       | region 3.
 * 
 * It is also possible to add step sounds to the events movement. To do 
 * this add the following note to them:
 * 
 * Event Note Tag:
 *   <stepSound>
 *       | Just by inserting this note in an event it will emit step sounds 
 *       | when moving.
 * 
  * Plugin Commands:
 *   Player Step Sound
 *       | This command allows to set if the player will emit step sounds
 *       | or not.
 * 
 *   Followers Step Sound
 *       | This command allows to set if the followers will emit step sounds
 *       | or not.
 * 
 *   Event Step Sound
 *       | This command allows to set if the event will emit step sounds
 *       | or not. When the id is 0 it will be applied to the current event. 
 *       | Else, the event of the defined ID.
