Update changelog with list of definitions added and removed since 0.10.0
Update changelog with list of definitions added and removed since 0.10.0

I used:

    git diff v0.10.0...master --name-status --diff-filter=AD share/php-build/definitions/ | sort

And then edited the list. It might be better to script this and do it
when tagging a release.
