Merge commit 'da9de7b6f03729f0f2de887abf71f983e8b0a881' as 'sites/all/modules/menu_attributes'
Set version of menu_attributes module: 7.x-1.x
Moved the subtheme to a new name
Bases for menus - correction made in bootstrap menu-link.func.php but at term should be transposed to bootstrapdreve/template.php
First menu functionnal and positionned, still need to play with dropdown
