fixed attribution of .fa-hand-pointer cursor color scheme to ordering according to token-drop sequence instead of seat sequence; updates to accomodate this throughout apps.epic.models & .views, plus new apps.epic migration; assigned #id_sig_cursor_portal a z-index value corresponding to a high position but still beneath the #id_tray apparatus; minor semantic reordering of INSTALLED_APPS in core.settings
