Joe Downing 92fa17660f Fixing the error logging in desktop_capture for Windows
The desktop_capture code logs failed HRESULTs in several places,
the problem is that it tries to use a wchar* (when a char*
is required) for the error message and doesn't display the HRESULT
in hex.  This makes the error logging less useful than it could be.

Example failure: error 08406B28, with code -2005270488

In this CL, I add a simple utility function to convert a _com_error
object to a std::string whic can be logged.  With this change the
output looks like this (linebreak added for CL description):
Failed to capture frame: HRESULT: 0x887A0026,
                         Message: 'The keyed mutex was abandoned.'

I also adjusted the formatting of a few logging statements to be
more consistent (adding '<<' operators mostly).
