Generated target files

[ggiamarchi]

Currently, templates are useful to generate text files in the target filesystem. It would be great to have a similar concept to generate binary file (or arbitrary file).

The idea is to introduce a new concept, let's call it a "generator" at the module level (like files, templates and scripts). Basically, it would contain scripts that generate files. One script generate one file.

Generator would be organised in a tree (exactly like templates). For instance the script generator generator/var/lib/data.bin.sh would generated a file /var/lib/data.bin
