INSTALL: Describe dependency knobs from Makefile
We said that some of our dependencies were optional, but didn't say how to turn them off. Add information for that and mention where to save the options close to the top of the file. Also, standardize on both using quotes for the names of the dependencies and tabs for indentation of the list.
