Recommendation is to avoid using the year nomenclature as this
information is already encoded in the git repo. Avoids needing to
repeatly update.
Also updates AUTHORS.txt from current repo with contributor names
* in DIALOG_EDIT_LIBRARY_TABLES::TransferDataFromWindow(), m_contentPanel->TransferDataFromWindow
* is explicitly called to update library tables.
* Before wxWidgets 3.1.x, m_contentPanel->TransferDataFromWindow is not called by wxDialog::TransferDataFromWindow()
* and explicit call is needed.
* Since wxWidgets 3.1.x, m_contentPanel->TransferDataFromWindow is called by wxDialog::TransferDataFromWindow()
* thus creating two successive calls, not supported by m_contentPanel->TransferDataFromWindow.
* The call to wxDialog::TransferDataFromWindow() was just removed, as it is useless in this dialog
