adding composer file to make slippy installable through composer

[dbu]

would be helpful if we could install slippy through composer, even though its not reusable code in the current form.

[dbu]

please tell me if i missed anything in the composer file that you would want there.

my plan is for the symfony-cmf-website to put the slides source html into the repository, have slippy as dependency and define a composer task that is run on install / update and calls the CLI mode of slippy to compile all slides in our folder into the web folder. seems the easiest way to get this integrated in a symfony project.

OK, not sure I got the whole thing but sounds reasonably harmless to this repo anyway so no worries, if you can just fix the license I'll happily merge

[dbu]

ups, fixed the license. i hope that was the right one?

please also register the repo with packagist so i can use it - but you of all persons know that :-)

[Seldaek]

I believe that's the right one yes, thanks!

[dbu]

well thank you :-)

as you can see i still use slippy.
