* Fixed const correctness error in Location

* Reworked ExportMainDialog in preparation for the creation of CD and region export dialogs:
  * Separated ExportPresetSelector and ExportFileNotebook from ExportMainDialog
  * Made ExportTimespanSelector polymorphic regarding single/multiple timespan mode
  * renamed ExportMainDialog to ExportDialog and made it easily customizable
  * created ExportRangeDialog and ExportSelectionDialog, these can be later customized more if necessary
