Fix Before Release.md

Major

• Fix case sensitive variables. right now, can't refactor all names that don't match the same case
• Finding scope for sqf variables, especially with loops
• kayler-renslow#39

Mild

• This is broken again (scope)

  _i = 100;
  for [{private _i = 0}, {_i < 5}, {_i = _i + 1}] do {};
  hint str _i; // 100
  

• private doesn't work very well inside spawn

Minor

• kayler-renslow#37
