guide installer instructions changes to text

"IMPORTANT: In the TeamSpeak installer, select “Install for all Users” and leave the default path!!!"
should probably be changed to reflect that using "for this user" is acceptable (confirmed working), at least without the script. (unknown if the script is working that way).
should DEFINITELY add note that if installing "for all users", you MUST choose the config location to be "same as install location", as not doing so makes ACRE2 not install its plugin at all. Changing that one setting fixes everything for an "all user" install.

for this user shouldn't work since it would install into AppData instead
