Issue #701 - Add the ability to embed the GIMP built-in sRGB profile...

...upon exporting an image

Step 1: make it configurable just like "Export EXIF" etc.

app, libgimp: add "export-color-profile" config option

Add it to the preferences dialog, and pass it on to plug-ins in the
GPConfig message. Add gimp_export_color_profile() to libgimp.

Nothing uses this yet.
