Enhanced the metadata functionality.
Added a quality section to the regular ASF metadata. Updated the 'meta2xml' tool accordingly.
Added an -iso and a -logfile option to meta2xml. That way we can add a number of parameters to the resulting XML that can be mapped to an ISO compliant metadata. The logfile provides time information for the individual processing steps.
Rename asf_convert_gui to mapready and asf_convert to asf_mapready.
More renamings for mapready and asf_mapready.

Also update SConscripts for mapready and asf_mapready to reflect the renaming.
Restore missing gmodule-export-2.0 link flags that broke mapready at runtime.
