* CH53 Fastroping and Fixes
Added fastrope points for CH53.
The getOut EH is required to keep the doors open when a unit exits the
vehicle and it uses the vehicle animation "doorHandler_R" or
"doorHandler_L" as a placeholder to determine if the doors are
open(1)/close(0).
eg. In UH1Y (Unarmed), when the right door is opened using the
useraction, "doorRB" and "doorHandler_R" will be set to 1.
* Changed TAB to 4 spaces
* Moved bracket to follow guidelines
* Optimizations with private, params, and isEqualType
* Fixed tab being used instead of space
* Fixed tabs inserted by notepad++
* More usage of new private syntax and params
- changed a few checks for an array being empty to `_arr isEqualTo []`
rather than `count _arr == 0`
- added more uses of `private` on the same line as the variable is
declared
- added more uses of params to assign variables passed as parameters
- removed unnecessary parentheses
- removed several unnecessary variable declarations with private array
syntax
* clean up and formatting
