 version =" 3.5"
 --[[
 Release Note:
 3.5:	Added:	Multiple item slots system, including the items to throw (suggested by Portsanta and CyanideEpic)
 		Major interface enhancements to make the configuration faster in spite of the new options
 		Enhanced item shortage security, supporting the multiple slots
 		New functions to manage I/O in a more compact way (suggested by Niseg)
 3.41:	Fixed:	Important glitch when the turtle returned to its starting position with a certain configuration
 		Displaying issues
 3.4:	Added:	Favorite configuration system
 		Ability to choose the direction of the series of parallel tunnels (right or left)
 		Support of execution without torches or chests (will not try to place them)
 		Security that stops the turtle when it runs out of chests or torches (suggested by CyanideEpic)
 		Chests and torches status updated automatically
 		Security that requires the user to press enter before the turtle starts (suggested by CyanideEpic)
 		The turtle now returns to its starting position after it finishes
 		New rotation function as well a a specific torch placing function
 	Fixed:	The turtle will now properly finish the hub after mining an odd number of tunnels
 		The torch placement has been modified to avoid conflicts with chests
 3.3:	Added:	Enderchest Support (suggested by Niseg and Daniteh)
 		Release note
 3.2:	Fixed:	Very important chest placing issue (only appeared in 3.1)
 3.1:	Added:	New mining pattern for more efficiency (suggested by Niseg)
 		Smarter fuel management:	Will now consume the "stored" fuel before refueling
 						Can now consume any type of fuel supported by turtles (check the wiki)
 						Fuel type can be changed while the turtle is mining
 		Optimized the mining of 3 blocks high tunnels
 		Better interface, instructions remain visible and a line is dedicated to the fuel status (updated automatically)
 		Option to throw cobblestone automatically (suggested by Niseg)
 	Fixed:	Refueling issue in certain circumstances (reported by CyanideEpic)
