crofty 0.16.0 — catch a theme cache that git would commit

crofty regenerates its theme under .crofty/themes/ on every build. If git tracks that folder, it gets committed and churns your history each time you build.

Before

The build hinted about .gitignore only when the file was missing entirely. A site that had a .gitignore without the /.crofty/themes/ rule was missed — so the regenerated theme kept getting committed with no warning.

After

crofty build now asks git what it actually ignores, not just whether a .gitignore exists, and tells you what to do:

• if the theme is already committed, it shows git rm -r --cached .crofty/themes/ plus the line to add to .gitignore
• if it’s simply not ignored yet, it shows the line to add
• if git already ignores it (or the site isn’t in git), it stays quiet

It only ever hints. It never edits .gitignore or touches git for you, and .crofty/config.json stays tracked — the build needs it and it holds no secrets.
