Bad import declarations cause kernel to die

[edechter]

IHaskell console does not recover from bad import declarations. For example:

edechter@helmholtz IHaskell (completions) $ IHaskell console
Python 2.7.2 (default, Oct 11 2012, 20:14:37)
Type "copyright", "credits" or "license" for more information.

IPython 1.1.0 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

IPython profile: haskell

In [1]: import
["import"]
Import: import
IHaskell: parse error (possibly incorrect indentation or mismatched brackets)


kernel died, restart ([y]/n)?

In [1]: import Data.Lizt
["import Data.Lizt"]
Import: import Data.Lizt
IHaskell: Failed to load interface for `Data.Lizt'
Perhaps you meant
  Data.List (from base)
  Data.DList (from dlist-0.5)
  Data.List (needs flag -package haskell2010-1.1.1.0)

Now the kernel doesn't die and we get an error message instead.

This is fixed in the commit 9516c70

Also, statements are now evaluated in order, and execution is stopped after the first error.
