MSF started to the extended API with window enum

Decided to kick off a new extended API extension with mubix and
kernelsmith to include some more advanced enumeration stuff. The goal of
this extension is to take stuff that wouldn't be part of the std api but
is rather useful for enumeration of a target once meterpreter has been
established.

This commit kicks things off with enumeration of top level windows on the
current desktop.
Add service_enum to the ext_server_extapi extension

This commit adds the ability to enumerate services on the target machine,
showing the PID, the service name, the display name and an indication of
the service's ability to interact with the desktop.

Some other small code tidies were done too.
Add service_query to ext_server_extapi

Once the user has queried the list of services they can now use the
`service_query` function to get more detail about a specific service.
Improve extapi ruby structure, add bins

The extapi project will get bigger over time so this change allows for the code to get
bigger without becoming a headache before it starts.

Added binaries to this commit as well.
Add support for child window enumeration

Children of windows can now be enumerated via the -p parameter, which
specifies the handle of the parent window to enumerate.

There is also a -u parameter which includes unknown/untitled windows
in the result set.
Add the start of clipboard support

This commit adds support for getting text-based information from the
victim's clipboard and for setting text-based data to the victim's
clipboard. Early days, with much wiggle room left for extra fun
functionality.
Add CF_HDROP file support to the clipboard

`clipboard_get_data` has been changed so that raw text is supported and file listings are supported.

If files are on the clipboard, those files and folders are listed when this command is run. To download the files, pass in the `-d` option.
Add size (bytes) of the files on the clipboard

Output of the `clipboard_get_data` call now includes the size
of each file in bytes.
