Subject: [PATCH] Add ExtUI::onStatusChanged_P function

It copies the parameter to SRAM and passes it to ExtUI::onStatusChanged (similar
to ExtUI::onUserConfirmRequired_P).

The call to ExtUI::onStatusChanged in `pause.cpp` was passing a PROGMEM pointer
in place of an SRAM one. It's now using ExtUI::onStatusChanged_P.
