no monster bashing anymore!

add a new way to target several enemies (only used when melee attacking for the moment)

refactor the targeting interface

the targeting interface is now more abstract and takes as a parameter a callback function which is executed when a target is selected

replace the Inventory class by a simpler array

targeting interface : add possibility to move the target even in non reachable tiles

remove unnecessary quote marks in the dictionnary

add numpad controls to the targeting interface

add distance weapons, add two new commands : l and r, add Animation class

add an afterThrow() method to Item

AI : add the possibility for a state to have several outcomes, add a weighting system, build a basic test behavior

rename Utils.js to utils.js, rename FiniteStateMachine.js to StateMachine.js, add some minor AI changes

add a minimalist animation to the throw action

change the way to go to the next turn

I forgot to add the main file of the last commit u_u"
