Keep a ChangeLog of update operations

[bergie]

Midgard MVC installation and updating commands should keep an automatic change log of the operations done. Basically I'd like to see something like:

Component updates:

  * midgardmvc_ui_create:
    * static/js/objectmanager.js: Append ID if it is set
    * static/js/containers.js: Add missing semicolon
    * workflow/action/delete.php: Delete attachments and parameters separately
  * net_example_website:
    * templates/ROOT.xhtml: Change site logo

Database updates:

  * midgard_attachment: table updated

PEAR upgrades:

  * zetacomponents/Foo: installed version 1.2.3

Preferably in a machine-readable (and human-readable) format, for example YAML.

Here is a Python example for how to generate changelogs from Git commit log:
