haskell-base64-bytestring: downgraded default version to 0.1.0.3

Browse Source 
Michael Snoyman reports that version 0.1.1.0 has serious performance issues:

> import Data.ByteString.Base64
> import Data.ByteString.Char8 (pack)
> import Criterion.Main
>
> main :: IO ()
> main = defaultMain
>    [ bench "encode" $ whnf encode $ pack "qwerty"
>    ]

On version 0.1.0.3, this takes 229.4312 ns. On 0.1.1.0, it takes 3.556598 ms.
It looks like the problem is coming from the recent addition of URL encoding
(f1916d8a86).
