Fixed a logical bug in mutual exclusiveness/group function.

Fix a single letter case sensitivity bug that causes group mutual exclusiveness functionality to not work

finally added tag and thumbnail

attempting to add a mod thumbnail

Add lots of comments and notes into XCom_Sitrep_Categories.ini hoping to help people unfamilar with the old Multiple Sitreps mod to understand how to set config for the new sitrep pulling method.
No change to the mod coding. Only config file XCom_Sitrep_Categories.ini is changed. I probably won't change the XCom_Sitrep_Categories.ini again so people don't need to reconfig the file.

I noticed that steam just added a discussion forum page for the mod. Any furthur config question should go there so comment section don't get spammed.


Below is the most important note I added imo:
***************IMPORTANT*****************
Quick summary of the new sitrep pulling process:

The new code first did some RNG simulation to determine how many sitreps should be added to a mission using SitrepChance and SitrepAmount, and let's call this result "x".
Then it find all sitreps from the game, put them into a list, and shuffled them.
when running through the shuffled list and checking sitrep to determine if it can be added, the mod checks the following:
if Categories is not "On", it ignores everything and just picks the first x sitreps in the random list.
If Categories is "On", it first checks mutual exclusiveness as determined by the group information,
then it checks which categories the current sitrep being checked is in.
(Note: this includes uncategorized category if you set UncategorizedInclude to "On". if you set it to "Off", it will ignore uncategorized sitreps")
It then finds the corresponding chance set in this category and rolls a dice to determine if this sitrep should be added.
The algorithm keeps going until x sitreps have been added or the list has been run out.
