removed now useless touch target, added distclean
bumped version "0.1"->"0.1-git"
fixed (define var val), strings still broken
skipitem for ( will no longer be able to skip over end of input
now has all the four basic arithmetic operations
added initsym.h
only prints "eof" if stdout is a tty. added a much nicer system for initializing the symbol table
totally pointless change
