guy & reqman : big releases

First post of 2020 ;-)

guy (0.6) & reqman (2.4) were released. Big changes in theses 2 modules. But compatibility is here ;-) (see respectives changelogs.md)

Confinement is good, but less time to explain more ;-)

Now, I should explain all changes in the respectives documentations (guy and reqman). Lot of work ;-(
