Pointfree refactoring tool

Stand-alone command-line version of the point-less plugin for lambdabot. 
Detailed information about the use of this tool is available at

Integration with GHCi: Make sure that the directory containing the pointfree 
executable is in your PATH environment variable and add the following line to 
your GHCi configuration file:

:def pf \str -> return $ ":! pointfree \"" ++ str ++ "\""

Or modify the line to point directly to the executable. Invoke pointfree with 
commands like

:pf \x y -> x + y


Not all of the testsuite passes, but one failure is due to a bug in HSE (see ) and many of the 
others I'm not sure if they ever succeeded, and are mostly failures to 
optimise, rather than actual correctness bugs.

Future directions

It would be nice to make pointfree a library that operated on ASTs, or at the 
very least on strings.
