====== Ma config d'Awesome ======
Voici une config pour awesome. 
Y'a plus de commandes et de widgets qu'utilisés. Certaines commandes sont précédées de "--", c'est parce qu'elle fonctionnent (je les ai testées), mais qu'elle ne me sont pas utiles pour mon usage actuel... Les choses étant changeantes, je les conserve, on sait jamais. Et puis ça peut être utile...

Il faut avoir installé les awesome-fonts (qui n'ont rien à voir avec Awesome le WM...)
