. manager.cpp : fixed the bug when stopping a program (broke in my last commit)
. *interfaces : beginning of event handling
. parsers.cpp : fixed memory leaks
. localinput.cpp : fixed memory leak

There is still a fixed memory leak at start up due to flex but during a
streaming process, all the memory is correctly free'd.

vls now stops correctly when Ctrl-C but there are few other bugs to
correct for the shutdown command.
