Worked on Castle.h, reworked image directories

For Castle.h:
added code allowing for the display of different castle types with
pre-established stats
added code allowing for the display of different castle offenses with
pre-established stats
Castle.h now has a health variable

For image directories
renamed directories to be more clear as to their contents
renamed images to be less wordy

note: this code hasn't been compiled so some of the file paths / logic
may be wrong
