Add use cases for each tor-launcher option.
It's pretty common to hear things like "I don't know what any of the 'Configure' options mean." It would help users if each Tor launcher option briefly described a situation where using it would be necessary. For example:
This computer needs to use a proxy to access the Internet. Only select if you can't use your regular browser without setting a proxy.
This computer goes through a firewall that only allows connections to certain ports. This applies at some universities and large companies.
My Internet Service Provider (ISP) blocks connections to the Tor network. Users in China need this option.
These are only examples of how the strings could be modified.
