====== Death GUI ======

Death gui works as following. When PC falls below 0 hitpoints, but is still over -10 he is in dying state. This will set ''Dying'' variable on PC and knock him down. This also summons the ''SCREEN_HIDDEN_DEATH'' screen on the display (full screen invisible window). If PC then left clicks anywhere on the screen ''gui_death_hidden_click'' script is called. 

''gui_death_hidden_click'' will then dismiss all death screens (''SCREEN_HIDDEN_DEATH'' and ''SCREEN_PARTY_DEATH'') and check if PC is still dying and if so will pop up ''SCREEN_PARTY_DEATH'' screen having options **Respawn**, and **Wait for Help**.

If PC clicks **Respawn** then ''gui_death_respawn'' is called. This will respawn PC and transfer him to starting location. If PC clicks **Wait for Help** then ''gui_death_waitforhelp'' is called. This will simply hide death screen and summon the hidden death screen. 

If during any time the PC actually dies (and no alive party members nearby) then normal ''SCREEN_PARTY_DEATH'' is shown immediately. PC has same options as above.

FIXME We need later to add support that DM can disable respawn button.
