Remove Neckbeard reference in favor of Advanced

At the risk of being over-sensitive because I do actually think the term neckbeard is amusing, the reference is:

- exclusionary of women, many of which who are more intelligent with their shell profiles than myself
- confusing/not as accessible to non-native English speakers

I think Advanced Configuration is more accessible and doesn't run the risk of offending anyone.

Sincerely,
Some guy with a really nice neck beard in real life and significantly less talent in shell profile "neckbearding"
