Added basic tooltip functionality. 

Conflicts:
	deps/tooltip.js

IPython has a tooltip feature which shows an info box under the cursor containing info about the current object. I have ported this to IHaskell. Basically, tooltip.js sends an object_info_request message to the kernel and the kernel responds with type information about the closest object.

make completion lexing slightly more reliable

Readme changes

Fix up complete_reply messages (#8).

The reason that aavogt's complete_reply messages were not showing up is because the "Messagin in IPython" documentation is missing a field for the complete_reply messages. There needs to be a "matched_text" field which contains the part of the line on which completions were computed. I have added that field and it seems to work now.

FYI, I figured this out because tab completion on the notebook was raising javascript errors in the browser. For future reference, this could be a useful thing to check if something in the notebook is not working.

Clarified the difference between cabal repl and calling ghci directly and added additional language pragmas into the .ghci file.

documentation update

descriptions are copied from README mostly, but a couple
were missing from there

The cabal file keeps track of the options necessary to install the package successfully. Running cabal-dev ghci will automatically take the cabal file options into account when launching ghci. Therefore, it is probably preferable to maintaining your own .ghci file.
