Update Genres Usage

About this plugin

The page must have at least one of the following section hierarchies with the following names and elements within them:

- info (section)
    - genre (section)
        - genre name (shape with text)   <----|
    - game (section)                      (connection)
        - game name (shape with text)    <----|

Genre name must be connected to shapes containing game names and only to them.

For example we have such structure:

"info" section _______________________________________
|
| "genre" section _________________________
| |                                       |
| |  "genre name 1"        "genre name 2" |
| |_________|_____________________|________
|           |-------------------> |
| "game" s._|____       "game" s._|_____
| |         v   |       |         v    |
| | "game name1"|       | "game name2" |
| |______________       |_______________
|
|_______________________________________________

After the update, it will look like this

"info" section _______________________________________
|
| "genre" section _________________________
| |                                       |
| |  "genre name 1"        "genre name 2" |
| |     (2/2)                   (1/2)     |
| |_________|_____________________|________
|           |-------------------> |
| "game" s._|____       "game" s._|_____
| |         v   |       |         v    |
| | "game name1"|       | "game name2" |
| |______________       |_______________
