[TYPO3-mvc] learning ExtBase... example exts

[Christian Zenker]

Just to also mention my "baby" cz_simple_cal.

https://github.com/czenker/cz_simple_cal (official git repo)
http://forge.typo3.org/projects/extension-cz_simple_cal (bugtracker,  
deprecated repository)

Highlights from the developer point of view are:
  * inclusion of tt_address domain model
  * scheduler task
  * overriden controller action

Have fun.

Christian.
