Support installing profile

Now, EasyKernel supports installing a .tar file containing it's ipython
profile, which includes information about how to launch the executable.

Add automation for easily defining kernels

The module IHaskell.IPython.EasyKernel provides automation for writing
simple IPython kernels. In particular, it provides a record type that
defines configurations and a function that interprets a configuration as
an action in some monad that can do IO.

The configuration consists primarily of functions that implement the
various features of a kernel, such as running code, looking up
documentation, and performing completion. An example for a simple
language that nevertheless has side effects, global state, and timing
effects is included in the examples directory in a file called Calc.hs.

Presently, there is no automation for creating the profile in the
.ipython directory. One should follow the IPython instructions for this.
