Consider top level domain name modification (customization)

[doostinharrell]

There has been a lot of talk on the web about what top level domain names should be used for local development. The research that I have done indicates that .text, .example, .invalid, and .localhost are reserved and would be great long term top level domain names to be considered.

This change would be made in the placeholder.aliases.drushrc.php for each of the templates.
