Use the new command-line parsing constructor for SystemExec to construct
the args array for the post-export hook from the entered command string,
with some simple substitutions for filename, directory, &c.

A few things need to be tested / completed:-
1) The code is currently guarded by #ifdef COMPILER_MSVC. This is just precautionary. If it builds okay with MinGW ,the guard can be removed.
2) Windows Playback and Capture devices almost always have different names. This needs to get accommodated in our Backend dialog (as in Mixbus)
3) Windows Playback and Capture devices will almost always contain spaces. We need to accommodate this when writing to .jackdrc (surround them in quote marks)
This is needed for gain and pan automation buffers
as well as silent and scratch buffers when bouncing or
exporting with larger chunk size than the current engine
period.
Re-arrange the items in the Soundcloud panel into a more sensible order &
arrangement, and add a (not-yet functional) tick-box to set the uploaded
files to be downloadable.
Rename the Soundcloud-related members of ExportHandler to all begin with
soundcloud_, and rename a couple of members of SoundcloudExportSelector
too for consistency.

Add soundcloud_upload property back into ExportFormatSpecification, but
instead of making it settable in the export format specification dialog,
add a tick-box in each tab of ExportFileNotebook to allow setting it.
Remove the Soundcloud upload property from export formats - it doesn't
belong there, since it's a thing which can apply (or not) to any format
preset.
