Inventory Tooltip

Thanks to the combined efforts of @niamu and myself hawkthorne now had a working tooltip for the player's inventory!

This addresses #1722 and #1959
To make the tooltip useful it displays pertinent stats about the selected item as well as a small description.  To improve readability of the tooltip, colored text has been implemented using the Tasty Text library (https://github.com/markandgo/text.lua).  Colors for the text were determined by examining the text pallet of the episode (http://imgur.com/a/ElSQI#15). Crafting results can also read by the tooltip before they are added to the inventory.  The tooltip is opened with the jump key.

edit: I added a small description to each item in the game which is why the files changed number is so high
