Rename local variables

Avoid confusion with the global 'deck[]', with which we are about to
do some refactoring.
Make deck responsible for timecode init

First step in making the code a bit more logical here, but we are
going to have to pass a lot more variables into the 'deck'.
Make deck responsible for the protect flag
Make deck responsible for importer
Refactor deck creation

Make it easier to create decks in other parts of the code.
A dummy deck for testing
Be explicit, now that the code is only used for one flag
Add missing gitignore entries
Correct example

The dicer flag is now in the 'long' format.
