[x2go-i18n] Swedish translation for x2goclient

Hi. Attached is the first version of the swedish translation for x2goclient. I couldn't verify the translation since the build scripts seem to be broken, this is the result when running config_linux.sh: RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_de.qm' RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_fr.qm' RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_nb.qm' RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_ru.qm' RCC: Error in 'resources.rcc': Cannot find file 'x2goclient_zh_tw.qm' Cheers, Daniel
