consistent function naming

[robertluo]

The names of functions/macros in monads.core namespace are not so consistent, some starts with a 'm', like mdo, mfail, some does not, like tell, asks. What if remove all the 'm' prepend, encourage user to do so:

(require '[monads.core :as m])
(m/do ....)
(m/fail ....)
(m/tell ....)
