`dump-core` a prettier GHC core viewer

[Iavor Diatchki]

Hello,

sorry about the link mix-up, the second one was supposed to be a link to
the GitHub:

https://github.com/yav/dump-core/

The README.md, which is rendered on GitHub, has instructions on how to use
the plugin, and I just updated it with some more information on how to use
the rendered HTML.   You can have a look at a sample rendered module here:

http://yav.github.io/dump-core/example-output/Galua.OpcodeInterpreter.html

The most striking thing everyone seems to notice first is that there are
many variables that have the same name---this is because I am only
rendering the string part of the names, without the uniques.  The hovering
behavior does use the uniques though, so that's what I usually use to
disambiguate the variables.   It would be easy enough to show the numbers
if people would like that.  I am sure that there are many other things that
can be improved---if you have ideas / suggestions, please file an issue on
github.

Cheers,
-Iavor
