This is a far cleaner way to provide *some* floating-point support. We
can only represent signed integers up to 2^51 rather than 2^63. But in
exchange we don't have to worry about it elsewhere, and it's probably
faster than checking tag bits in every operation.
Hmm, yeah, surprised how easy this was. I think I'll give up on the
other approach.
I still don't have non-integer literals. But we won't bother with those
until we need them. `3.14159:literal` seems ugly.

I added one test to check that divide can return a float, then hacked at
the rippling failures across the entire entire codebase until all tests
pass. Now I need to look at the changes I made and see if there's a
system to them, identify other places that I missed, and figure out the
best way to cover all cases. I also need to show real rather than
encoded values in the traces, but I can't use value() inside reagent
methods because of the name clash with the member variable. So let's
take a snapshot before we attempt any refactoring. This was non-trivial
to get right.
Even if I convince myself that I've gotten it right, I might back this
all out if I can't easily *persuade others* that I've gotten it right.

On my ubuntu 14.04.1 + gcc 4.8.2 machine, ifstream doesn't actually
raise an error on trying to open a non-existent file until you try to do
something with it. Garbage!

Also a bugfix in break to label, because I noticed the screen wasn't
being cleaned up on quit.

I tried to bring too much into this commit, and paid the price with some
debugging effort. Still havent't tried to enable line buffering, but
I'll take a snapshot.
Some tests are failing because of the huge hack in the scheduler.
For a while I thought there was a bug in termbox because I kept seeing
segfaults and valgrind complained about out-of-bounds access. But that
was just subsidiary threads trying to print to the screen after I'd
returned to console mode.
Maybe I should add a test for send-keys-to-channel. Or just use a fake
keyboard rather than a channel.
And *then* there's the fact that the interaction is molasses slow.
Slower than the arc version even though the tests run so much faster.
And what's with the long pauses in printing strings to screen?
