[IMP] base: improve ir.module.module tree view

This commit simply improves the modules tree view by removing the tree
"decorators" and replacing it by a badge widget with associated decorators on
the 'state' field.

Indeed, the previous implementation could make the tree view look a bit "scary"
at first opening because it would color a lot of lines in red (modules were
not installed), giving it a feeling or "error" where there was none.

Now the color is directly shown on the state field, making it clear it's
related to that information.
