German translation added and UMIL updated

Hey,

thanks for your Advanced-Show-Poll-Voters MOD. I've added a german translation and fixed the englisch and spanish translation to make the ACL permission show up under the polls tab.

Additionally I added the translation files to ```install.xml``` and updated the version number of ASPV to 1.0.1 to prevent errors with the new files in the installer. You're homepage metioned in the installer seems to be broken, so I added the GitHub URL. Furthermore I updated UMIL to version 1.0.5.

Feel free to merge if you like ;-)
