change the number of posts required to change level.

BACKGROUND:
General ZeT found an error in the existing rank system, which was that his rank did not correspond to what it should have been according to the existing rank system.

WHAT HAPPENED:

WAS: * Level 1 - >= 1 post * Level 2 - >= 25 posts * Level 3 - >= 75 posts * Level 4 - >= 150 posts * Level 5 - >= 250 posts * Level 6 - >= 500 posts * Level 7 - >= 750 posts * Level 8 - >= 1000 posts * Level 9 - >= 1500 posts * Level 10 - >= 2000 posts * Level 11 - >= 3000 posts * Level 12 - >= 5000 posts * Level 13 - >= 7000 posts * Level 14 - >= 10000 posts

BECAME: * Level 1 - < 25 posts * Level 2 - < 75 posts * Level 3 - < 150 posts * Level 4 - < 250 posts * Level 5 - < 500 posts * Level 6 - < 750 posts * Level 7 - < 1000 posts * Level 8 - < 1500 posts * Level 9 - < 2000 posts * Level 10 - < 3000 posts * Level 11 - < 5000 posts * Level 12 - < 7000 posts * Level 13 - < 10000 posts * Level 14 - >= 10000 posts

At first glance, it seems that the changes are large and there has been a shift of one level, but this is just an illusion, and if you look more closely... using level 3 as an example:
* Level 2 - >= 25 posts
* Level 3 - >= 75 posts
* Level 4 - >= 150 posts
That is, to get level 3, you need to have more than 74 posts, but less than 150.
[75 <= Level 3 < 150]

* Level 2 - < 75 posts
* Level 3 - < 150 posts
* Level 4 - < 250 posts
That is, to get level 3, you need to have more than 75 posts, but less than 150
[75 < Level 3 < 150]

SUMMARY:

1. [75 <= 3 level < 150]
   [75 < 3 level < 150]
   The shift was not by one level, but by one post :)
2. The error found by General ZeT has been fixed.
