$GLOBALS['TBE_STYLES']['stylesheet'] and $GLOBALS['TBE_STYLES']['stylesheet2'] are rarely used in public extensions and we seem to have no current documentation about those two configuration settings.

Since we have $GLOBALS['TBE_STYLES']['skins'][$nameOfSkin]['stylesheetDirectories'] configuration in place to include custom stylesheets from extensions, the settings $GLOBALS['TBE_STYLES']['stylesheet'] and $GLOBALS['TBE_STYLES']['stylesheet2'] can be deprecated.
