// ==/UserScript==//

// ==Notes==
// Based on Pardus Trader Buddy by Tsarugi (Artemis)
//
// This works on one's own buildings.  It adds buttons to help stock your own
//   building for a given number of ticks.
//
// You are able to make changes to your own copy of the script once it is
//   installed.  <b>Please store a backup copy of your user options section
//   before you reinstall the script.</b> I encourage you to send code changes
//   and ideas for enhancements to me so I can update the master copy.  This way
//   everyone has access to helpful changes.  It also makes it easier for me to
//   give help if everyone sticks to the master copy.

// ==Version History==
// 1.0 Created on 3/18/2008
// --Added buttons on building trade screen:
//   'Send All' - Auto fills 'Ship' column with upkeep stock up to the max avaliable space in building
//   'Send to 5x' - Auto fills 'Ship' column with upkeep stock up to 5 ticks worth if space is avaliable in building
//   'Send to 10x' - Auto fills 'Ship' column with upkeep stock up to 10 ticks worth if space is avaliable in building
//   'Send to 15x' - Auto fills 'Ship' column with upkeep stock up to 15 ticks worth if space is avaliable in building
//   'Get All' - Auto fills 'Building - Commodities' column with produced commodities up to the max avaliable space in ship
//   'Easy Button' - does send and get buttons marked with a *, by default they are 'Send Items' and 'Get Items'
// --Buttons know not to send produced commodities back to the building and not to get upkeep stock from the building.
// --Buttons are aware of the mag scoop and will use the space if it is turned on.
// --Clicking on individual commodity name will auto insert max send/get value for the available space
// --Free space is tracked and displayed for building, ship, and mag scoop.  It accounts for manually entered values
//   and click-fill usage
