Replaced which with command -v since which is already deprecated

Fixed a couple of typos in the PortProton installation script

added a check for the existence of a symbolic link

If a person runs a PortProton installation when it is already installed e.g. if he installed PortProton manually and decided to switch to the package, the first installation will break because of the existence of a symbolic link and consequently PortPrototon will not run

Update script lang - №2

Заменил упоминание PortProton на переменную $portname
Привёл английскую локализацию к тому же виду что и русскую
Дополнил общую локализацию

Add description for all vkBasalt effects
