This is a correction of the PR #5. According to the comment I got I can remove hyphen-fi hyphen-ga hyphen-id from the list since they are dependencies of the openoffice.org-hyphenation package and are installed automatically. This resolves issue #4.
I also added a command to the script which sets the additional keyboard layouts (arabian and persian) needed via command line. This resolves Issue #5.
This commit adds the missing language-packages to script, so those don't need to be installed manually through mintlocale anymore, after this script was executed.
