Removes the optionality on output in ABI docs.

Browse Source 
I _believe_ (someone more knowledgable than I should verify this claim) that Solidity will always write out an `output` member.  If there are no return parameters, then the array will be empty, but the `output` property will be present.

If this is not correct, I will withdraw this PR, but if the assertion is correct then the docs should reflect that so people can rely on the `output` property being present when writing ABI processors.

I also fixed some inconsistency in line termination character.  It was sometimes `.` and sometimes `;`.  I picked `.`, but don't really care which as long as it is consistent.

The JSON format for a contract's interface is given by an array of function and/or event descriptions.
A function description is a JSON object with the fields:
- ``type``: ``"function"``, ``"constructor"``, or ``"fallback"`` (the :ref:`unnamed "default" function <fallback-function>`);
- ``name``: the name of the function;
- ``type``: ``"function"``, ``"constructor"``, or ``"fallback"`` (the :ref:`unnamed "default" function <fallback-function>`).
- ``name``: the name of the function.
- ``inputs``: an array of objects, each of which contains:
* ``name``: the name of the parameter;
* ``name``: the name of the parameter.
* ``type``: the canonical type of the parameter (more below).
* ``components``: used for tuple types (more below).
- ``outputs``: an array of objects similar to ``inputs``, can be omitted if function doesn't return anything;
- ``stateMutability``: a string with one of the following values: ``pure`` (:ref:`specified to not read blockchain state <pure-functions>`), ``view`` (:ref:`specified to not modify the blockchain state <view-functions>`), ``nonpayable`` (function does not accept Ether) and ``payable`` (function accepts Ether);
- ``payable``: ``true`` if function accepts Ether, ``false`` otherwise;
- ``outputs``: an array of objects similar to ``inputs``.
- ``stateMutability``: a string with one of the following values: ``pure`` (:ref:`specified to not read blockchain state <pure-functions>`), ``view`` (:ref:`specified to not modify the blockchain state <view-functions>`), ``nonpayable`` (function does not accept Ether) and ``payable`` (function accepts Ether).
- ``payable``: ``true`` if function accepts Ether, ``false`` otherwise.
- ``constant``: ``true`` if function is either ``pure`` or ``view``, ``false`` otherwise.
``type`` can be omitted, defaulting to ``"function"``, likewise ``payable`` and ``constant`` can be omitted, both defaulting to ``false``.

An event description is a JSON object with fairly similar fields:
- ``type``: always ``"event"``
- ``name``: the name of the event;
- ``name``: the name of the event.
- ``inputs``: an array of objects, each of which contains:
* ``name``: the name of the parameter;
* ``name``: the name of the parameter.
* ``type``: the canonical type of the parameter (more below).
* ``components``: used for tuple types (more below).
* ``indexed``: ``true`` if the field is part of the log's topics, ``false`` if it one of the log's data segment.
