* Fixed a regression in 'lib/rdreport.cpp' that caused RDLogManager
events to be omitted from reports even when the
'Export Event Types - All' checkbox was selected in combination with
'Traffic Log' or 'Music Log' checkboxes. [Fixes GitHub issue
#000021].
* Added 'REPORTS.POST_EXPORT_CMD' and 'REPORTS.WIN_POST_EXPORT_CMD'
fields to the database.
* Incremented the database version to 242.
* Added 'RDReport::postExportCommand()' and
'RDReport::setPostExportCommand()' methods in 'lib/rdreport.cpp' and
'lib/rdreport.h'.
* Added 'Linux Post Export Cmd' and 'Windows Post Export Cmd' controls
to the 'Edit Report' dialog in 'rdadmin/edit_report.cpp' and
'rdadmin/edit_report.h'.
* Implemented post export commands in 'lib/rdreport.cpp'.
