Merge ~xnox/ubiquity:subtree-squash into ubiquity:master

[Dimitri John Ledkov]

3rd option of subtree add --squash

This is similar to subtree, but instead of full history for every d-i component, there is just a single commit.

We can develop/merge/rebase repos in lp:~ubuntu-installer/$project as usual, and then just single commit update them in the ubiuqity repo.

This is closer to how "git add d-i/source" would look like, but with enough git subtree --prefix automation to allow easier subtree updates in the future.

This repository is the smallest, yet contains the full source code, as uploaded in dsc form.

[Dimitri John Ledkov (xnox)]

I feel like we dislike this option, as althought changes to squashed subtrees are allowed, they do not contain the full history, and one cannot pull/push/merge from these directly like one can from the full trees.

review: Disapprove
