Fixed devscripts.
Stripped Makefile.
Changed bytecode EOF value to 0F.

0F is equal to '^O', this character usually fixes a terminal after it's
been screwed up by displaying '^N'.
(They're ASCII control characters for Shift In/Out.)

If someone accidentally does `cat bytecode.slf`, the '^O' terminator will
help prevent their terminal from being screwed up afterwards.

protip: use "echo <ctrl-v><ctrl-o><enter>" for the same effect
