The JIT transplant carried over a yaps2 commit that forced softcore-only
achievements. Its functional half was correctly resolved away by the merge --
SetHardcoreMode, CanEnableHardcoreMode and the custom user agent are all stock
again -- but the Qt UI vestige survived: the settings page hard-coded
setEnabled(false) on the hardcore checkbox and told users hardcore was
unavailable.
Net effect: hardcore mode worked in the core but users could not switch it on.
Restores setEnabled(enabled) and the stock help text; the file is now identical
to master. The original commit's own message said to revisit this once yaps2
merged into ARMSX2.
