Lower requirements on http-conduit dependency

[17dec]

In my attempt to get haste-compiler to work with lts-6.31 I stumbled upon the http-conduit >=2.2 dependency of shellmate-extras. lts-6.31 comes with http-conduit-2.1.11.

shellmate-extras builds fine with that version, but I see you upped the dependency not too long ago in 9153cf1 - Is the a specific reason for requiring >=2.2?

I don't think there was any particular reason. Most likely I just intended to relax the upper bound, but accidentally tightened the lower bound as well. I lowered the minimum bound to >= 2.1 again in 2e204fc just now.
