 * -------------------------------------
 * Plugin Commands (not case sensitive):
 * -------------------------------------
 *
 * Stamina Refill
 * Instantly refills all of your stamina.
 *
 * Stamina Set <value>
 * Instantly sets your stamina to the specified percentage (0-100).
 * Example to set your stamina bar to 64: Stamina Set 64
 *
 * Stamina Deplete
 * Instantly sets your stamina to 0.
 *
 * Stamina ShowWindow
 * Shows the stamina window. Does not work if you disabled the stamina window.
 *
 * Stamina HideWindow
 * Hides the stamina window. Does not work if you disabled the stamina window.
 * Also does not work if the stamina is currently regenerating.
 *
 * Stamina RefillHide
 * Instantly refills all of your stamina and also hides the stamina window.
 *
 * Stamina SetMax <value>
 * Sets a new max-stamina value.
 *
 * Stamina IncreaseMax <value>
 * Increases max stamina by the specified value. You can also use negative values.
 *
 * Stamina EnableDashing <true/false>
 * Allows or prohibits dashing on the map.
 * -------------------------------------
 * Map Notetags
 * -------------------------------------
 * <dstam_disable>
 * Prevents stamina consumption on this map. Not that if the "Disable Stamina Consumption GameSwitch"
 * is turned ON then you consume no stamina anyway.
 *
 * <disable_dashing>
 * Prevents dashing on the map (with or without stamina).
 *
 * -------------------------------------
 * Item Notetags (not case sensitive)
 * -------------------------------------
 * <dash_stamina:command (value)>
 * Available commands:
 *  - Add (may have a negative value)
 *  - Refill
 *  - Deplete
 *  - IncreaseMax (may have a negative value)
 * Examples:
 * <dash_stamina:Add 10>
 * <dash_stamina:Add -10>
 * <dash_stamina:Refill>
 * <dash_stamina:Deplete>
 * <dash_stamina:IncreaseMax 1500>
 * Note that those only work from the menu, not from battle
 *
 *--------------------------------------
 * Version History:
 *--------------------------------------
 *
 * v1.02 (12 December 2015)
 *   - Dashing for the current map can now be entirely disabled with a map-notetag and switched with a plugin command at any time.
 *   - Created a simple plugin addon to store the player-stamina in a global game-variable.
 *   - Enabled custom text to be drawn in front of the Stamina Window.
 *   - New feature: items can replenish, lower, refill and deplete stamina (only in the menu, not in battle).
 *
 * v1.01 (1 December 2015)
 *   - Removed strict-mode because... Possible bug in RPG Maker...
 *   - Refactored and fixed semicolons and missing var-keywords.
 *
 * v1.00 (26 November 2015)
 *   - First release.
 * Alpha (November 2015)
 *   - First alpha release.
 *
