Add pack and unpack convenience scripts

[mkolar]

These scripts provide easier way to export a full project with database and all of it's data and subsequently load it back.

The most common use is for testing purposes. This makes it possible to export a current state of projects, do testing publishes and then return to the previous state. The result is a zip file containing everything needed for the project, so it is not suitable for packing full project at production scale.

Additional info

The pack project currently doesn't include project settings

Testing notes:

packing

1. run pack_project.ps1 with a project name as an argument.
2. you should be left with a zip file next to the project root folder

unpacking

1. run unpack_project.ps1 path/to/project.zip
2. check if the project has been unpacked and the original project folder renamed for a backup
