[minimod] Force Bughunt Turn 15

[Rangerh]

This is the 40K version of this OXCE minimod :
https://openxcom.org/forum/index.php/topic,7657.0.html

Basically it forces the bug hunt to always trigger exactly at turn 15  regardless of additional conditions that would either delay it or prevent it to trigger.
(you can easily edit this exact amount of turns for your own taste in the file bughunt_turn15_40k.rul )

You can get the minimod also part of the minimods collection for 40k/Rosigma :
https://openxcom.old.mod.io/minimods-collection-for-40k-and-rosigma

To install, download the attached files
Then extract the folder named :
bughunt_turn15_WH40K

And drop this folder into your
...\OpenXComDirectory\user\mods\

Then in the 40k main menu, go to Mods and set "BugHunt Turn 15 WH40K" to YES to enable it
(should be compatible with every future and old version of 40k )
