* Added some missed phrases.
* Added some missed files to the list.txt
* Fix for https://github.com/prusa3d/PrusaSlicer/issues/7114 - Reword of the "Ask for unsaved changes..."
* Fix for https://github.com/prusa3d/PrusaSlicer/issues/7542 - Added localization for default buttons Yes/No
Note: For some default buttons/labels/dialogs/... is used localization in wxWidgets.
But dictionaries have to contain this strings, otherwise texts wouldn't be localized.
"wxWidgets/local" contains dictionaries for all this default phrases.
So, a copy of this field is added as a "wx_local" field to the "resources/localization" field.
And a "gettext_concat_wx_po_with_po" script is written to concatenate strings from wx_local/lang_code.po to resources/localization/lang_code/PrusaSlicer_lang_code.po.
So, to create a MO file from updated PO we have to execute "gettext_concat_wx_po_with_po" and only then execute a "gettext_po_to_mo" script.
