/*
It hides options after winning an attack as per requirement.
To help people to not choose wrong option after winning an attack. 
Especially mobile players with fat fingers like me.
 *
 Use cases:
 1) Termed Wars where you can't hospitalise or mug the opponent.
 2) While doing missions when you are given specific instructions.
 3) If you are a mugger.
 4) Any other situation where you don't want to accidentally leave or hosp or mug.
 *
 *
 How to use:
 By default all options will be visible
 Before opening the attack page, set the options in lines 32 to 34 to:
 true, if you want that option to be visible
 false, if you want to make the option invisible.
 *
 Incase you forgot to change the settings before the attack there will be a "Show All" option to show all the options.
