5.2.0

  - Corrected handling of Color240 values.

  - Squashed warnings. Thanks jtdaugherty!

  - Config structure now specifies file descriptor to use. The default is stdInput and stdOutput

    file descriptors. Previously Vty used stdInput for input and the follow code for output:

      - hDuplicate stdout >>= handleToFd >>= (`hSetBuffering` NoBuffering)

      - the difference was required by Vty.Inline. Now, Vty.Inline uses the Config structure options

        to acheive the same effect.

  - removed: derivedVtime, derivedVmin, inputForCurrentTerminal, inputForNameAndIO,

    outputForCurrentTerminal, outputForNameAndIO

  - added: inputForConfig, outputForConfig

  - updates to vty-rogue from jtdaugherty. Thanks! 

  - the oldest version of GHC tested to support vty is 7.4.2
