MAL Public Score in MangaList

Adds new column with public score to the MangaList. WARNING! this script only works on Modern Lists, and, not the Classic ones (I think so)

MAL Public Score in MangaList was deleted due to: Report #50267.

Appeal submitted by the author:

Updated the script to terminate its execution if the MAL Score column has been enabled on the user's list.
People can now utilize this script to view the MAL Scores on lists where the user has NOT enabled the MAL Score column. This effectively rebuts the reporter's claims that the script is no longer necessary since the website already does this.

As a result of this appeal, a moderator undeleted this script.
