Tool
did some stuff
fixed merge conflict in tool sheds controller
reserve button subtracts one from available, doesn't go below zero
logic is in place on tool library page to hide reserve button if you've already checked it out
reserve/return buttons/logic work!!
tools you've checked out now appear in your account page, and names of people who have checked a tool out appear on the tools index
changed header alignment in tools index
