Dependencies and compatibility

[Ben Gamari]

Here is a patch allowing Scoutess to build on GHC 7.6. This both breaks
the dependency on old-time (replacing it with new time) and bumps the
lower bound on directory. It also bumps the upper bounds on Cabal,
bytestring, and network.

I probably could have added some CPP guards to preserve compatibility
with old-time, but I felt this would be a bit cleaner.

Cheers,

- Ben

I should note that I still haven't been able to get Scoutess to build
anything sucessfully, so this still isn't fully tested (beyond the fact
that it builds). In particular, I'm seeing,

$ scoutess vector-algorithms 0.5.4 Hackage sandbox sources.txt
scoutess: user error (You need to re-run the 'configure' command. The version of Cabal being used has changed (was Cabal-1.14.0, now Cabal-1.16.0). Additionally the compiler is different (was ghc-7.4, now ghc-7.6) which is probably the cause of the problem.)

Cheers,

Yeah, Scoutess' GSoC hasnt' been as strong as we would have wanted, and in particular it seems it worked for the student but none of us has been able to make it build anything. 

However, we are discussing a radical shift in the design/impl right now, to simplify our work and the contributor's work. Right after we decide which way to go (you can contribute to that discussion!), everything will evolve way faster.
