v1.1.1

• added mkdir as an alias of file.makedir
• added world.chat and world.chatMessages to allow bots and the home computer to interact with the in-game chat
• fixed an error that prevented bot.select from working with a tool index (thanks to GitHub user Zelec)
• the /usr disk and computer context are now properly reset when exiting to title
• you can no longer exit the bot UI while moving an inventory item (preventing accidental loss of the item)
