Do not prefix the configuration-value names with the module machine name

[avpaderno]

Prefixing the configuration-value names with the module machine is not necessary, as unique configuration-object names make impossible to have conflicts between configuration-option names from different configuration objects.

I am postponing this issue on #79. Before changing the configuration-values names, values that should not be configuration values need to be replaced by state values, at least to avoid to rename twice the same value. (State values must have names that avoid conflict with values used from other modules, while configuration values need to have names that are unique inside a configuration object.)
