Fix a crash in PreviewLoader for command-line xhtml output

Browse Source 
While exporting from the command-line, theApp() doesn't exist.
The colors foreground and background are only needed when
previewing, so ignore this during buffer export.

This replaces the fix in 4285b0b3 (Tommaso Cucinotta, 10-12-2012).
In this case, we do not need to pull in Qt dependencies.
