New src-* modules release : license change and some fixes

src-* modules of the websitesystem project focus on code generation from ad-hoc structured xml files. The goal is to relieve programmers from writing repetitive patterns of code.
Each module focus on a specific model, some modules depends on other modules to generate additional code.

The new release fixe some bugs, and I hope that these are the last ones, so that I can focus on writing some documentation. From this version (0007.10.18), these packages are licensed under the terms of the GNU GPL v3.
