Added file upload support

Browse Source 
It is now possible to send multipart/form-data requests.

Note that the --file option used previously has been removed
because it didn't allow you specify the field name.

Example:

    http -f POST example.com field-name@/path/to/file

http [flags] METHOD URL [items]
There are three types of key-value pair items available:
There are four types of key-value pair items available:
Headers
Arbitrary HTTP headers. The ``:`` character is used to separate a header's name from its value, e.g., ``X-API-Token:123``.
Simple data items
Simple data fields
Data items are included in the request body. Depending on the ``Content-Type``, they are automatically serialized as a JSON ``Object`` (default) or ``application/x-www-form-urlencoded`` (the ``-f`` flag). Data items use ``=`` as the separator, e.g., ``hello=world``.
Raw JSON items
File fields
Only available with ``-f`` / ``--form``. Use ``@`` as the separator, e.g., ``screenshot@/path/to/file.png``.
Raw JSON fields
This item type is needed when ``Content-Type`` is JSON and a field's value is a ``Boolean``, ``Number``, nested ``Object`` or an ``Array``, because simple data items are always serialized as ``String``. E.g. ``pies:=[1,2,3]``.

It is also possible to send ``multipart/form-data`` requests, i.e., to simulate a file upload form submission. It is done using the ``--form`` / ``-f`` flag and passing one or more file fields::
http -f POST example.com/job-application email=John cv@~/Documents/cv.pdf
The above will send a request equivalent to submitting the following form::
<form enctype="multipart/form-data" method="post" action="http://example.com/job-application" >
<input type="text" name="email" />
<input type="file" name="cv" />
</form>
A whole request body can be passed in via ``stdin`` instead::
echo '{"name": "John"}' | http PATCH example.com/person/1 X-API-Token:123
