matchure 0.13.0-SNAPSHOT for clojure 1.5

[fdserr]

Hi Drew,

here it is:

• version up'd to 0.13.0-SNAPSHOT
• compiled and tested against Clojure 1.5.1
• big number types (M suffix) do not match anymore against other numeric types
• the main namespace is now matchure.core
• mods and formatting in read-me.md
• NOT pushed to clojars, please tell me when you do, so I can upgrade too.

Take your time and don't hesitate to cut into it... Thanks again for this awesome lib!

François
