Embed git in package

package.ps1 fetches PortableGit and embeds it in the package. This
eliminates all but one runtime dependency (MSVC++ Redistributable).

* Move Python into a new FOSS folder.

-"""HTTP/1.1 client library
-
-A backport of the Python 3.3 http/client.py module for python-future.
-
-<intro stuff goes here>
-<other stuff, too>
-
-HTTPConnection goes through a number of "states", which define when a client
-may legally make another request or fetch the response for a particular
-request. This diagram details these state transitions:
-
-    (null)
-      |
-      | HTTPConnection()
-      v
-    Idle
-      |
-      | putrequest()
-      v
-    Request-started
-      |
-      | ( putheader() )*  endheaders()
-      v
-    Request-sent
-      |
-      | response = getresponse()
-      v
-    Unread-response   [Response-headers-read]
-      |\____________________
-      |                     |
-      | response.read()     | putrequest()
-      v                     v
-    Idle                  Req-started-unread-response
-                     ______/|
-                   /        |
-   response.read() |        | ( putheader() )*  endheaders()
-                   v        v
-       Request-started    Req-sent-unread-response
-                            |
-                            | response.read()
-                            v
-                          Request-sent
-
-This diagram presents the following rules:
-  -- a second request may not be started until {response-headers-read}
-  -- a response [object] cannot be retrieved until {request-sent}
-  -- there is no differentiation between an unread response body and a
-     partially read response body
-
-Note: this enforcement is applied by the HTTPConnection class. The
-      HTTPResponse class does not enforce this state machine, which
-      implies sophisticated clients may accelerate the request/response
-      pipeline. Caution should be taken, though: accelerating the states
-      beyond the above pattern may imply knowledge of the server's
-      connection-close behavior for certain requests. For example, it
-      is impossible to tell whether the server will close the connection
-      UNTIL the response headers have been read; this means that further
-      requests cannot be placed into the pipeline until it is known that
-      the server will NOT be closing the connection.
