Remove a rewrite rule that makes GHC 7.4.1 ill

The effect of the rule was to make isPrefixOf infloop; see [GHC bug
5783](http://hackage.haskell.org/trac/ghc/ticket/5783) for details.

This fixes gh-16.
Bump version to 0.11.1.13

Reduce the amount of code generated for string literals

Previously, every Text literal generated a big wad of inefficient
code:

    {-# LANGUAGE OverloadedStrings #-}
    foo :: Text
    foo = "foo"

This would first convert to a String, then to a Text.  To make
matters worse, the code for conversion from String to Text was
inlined at every site where a string literal occurred (expected,
but undesired, behaviour).

In this change, we introduce a direct conversion from Addr# to each
of the Text types, and we ensure that uses of these never result in
excessive code generation.

A small improvement in Text generation efficiency.

The specialised Run tuple avoids boxing and indirection for both
the MArray and Int parameters in the predecessor code.

I think I can do better, though.
Another try at improving Text generation.
