elexis 040624acff Replace copy-assigning GUI<T>::GetSetting from c2a71e41bf with the reference returning GetSetting from 3dfa23cd25.
Avoids one or two dozen unoptimizable string copies and two CPos copies,
mostly in SetupText.

The reference return allows to mark values as const where the previous
one prevented that.
This also reveals unused variables where the previous code hid them.

Thus use unused variable "buffer_zone" in the otherwise unused (since
b1422137e5, refs 0f807c643a) CCheckBox::SetupText() from b5f6d19332 and
use the unused variable "scrollbar" in CInput GUIM_MOUSE_PRESS_LEFT from
4113aa0a36.

Refs unintentionally copied DrawCall cache due to GetSetting copying in
c19f3608a5, fixed in 8f4f8e240f.
