Javascript - pretty-print and uglify JSON strings

/* Uglifier: */
/* this was suprisingly waay harder than prettifying. prompt() can't handle multiple lines so I had to improvise. Also I had to get a working regex that was valid in JavaScript that would strip spaces while leaving them alone inside quotes.*/
