build fails with ghc 7.10

[lilyanatia]

building fails with multiple errors. adding {-# LANGUAGE FlexibleContexts #-} to lib/Kitten/Tokenize.hs and changing elem "..." to elem ("..." :: String) in a few places (as described at https://ghc.haskell.org/trac/ghc/wiki/Migration/7.10) seems to fix it.

Thanks! I’ll get this in later today. Right now I’m working on integrating a new version of the typechecker into the existing compiler, so I haven’t been housekeeping.

Oops. Fixed in 1da983be65b87c3356a528dd25bdb5da5fd05420.
