Improving Contribution User Experience

Contributing to MacPorts for the first time is harder than it needs to be. We discussed an approach to simplify this for users by automating the switch to git-based source (without the long wait time to re-generate the PortIndex from scratch).

A question-and-answer based flow could look similar to this:

$> port <edit|bump> foobar
---> ${thing}ing foobar
You do not seem have a working copy of the macports-ports git repository, which
is required to contribute this change. Create one now? [Y/n]: Y<CR>

Where do you want to create your working copy? [~/macports-ports]: <CR>

The 'macports' user needs search access to ~/macports-ports to use ports in
this directory. The following directories will be changed to include 'x'
permissions for group and others:
 - /Users/$me/macports-ports
 - /Users/$me
Do you want to allow this? [Y/n]: Y<CR>
