Feature: Ability to add prefix to repo names in clone URLs

[fredcooke]

Ability to add prefix to repo names in clone URLs (and optionally on disk folder names) where those URLs don't already start with the prefix and don't match the prefix minus any trailing hyphens. For example, for the following repo set:

cyberdyne
cyberdyne-headquarters
terminator-franchise-service

And the prefix cyberdyne- only the last of the three would be modified by adding the prefix. The first matches the trailing-hyphen-less rule and the middle one already has the prefix.

It'd also be nice to make the directory tree match what it would be like if the names had applied the entire time.

However I'd also like to see the ability to put the repos on disk without the prefix to match every other location such as the pom artifactId for Java tooling and similar. But that's for another issue and another day.
