Packaging script

1. composer install should work without DB credentials
2. composer create-project should not warm any caches (as those would wind up in the created ZIP)
3. something like:
   composer create-project phplist/base-distribution phplist 4.0.x-dev --prefer-dist --no-dev --stability=dev
4. automatically create a TGZ with the version number in the file name

We might also use an approach similar to https://github.com/bmack/typo3-darth (although smaller).

"composer create-project should not warm any caches (as those would wind up in the created ZIP)"

Instead of trying to change how symfony caching does the warming up of the cache how about just excluding var/cache and 'var/logs` from the archive?
