Title: Refactor config loading

**Note:** *Please merge #60 first.*

This serie of patches refactors the loading of the configuration file: all variables used during config evaluation are defined in the scope of the `_lp_source_config` function.
This refactoring makes it clearer (for further code maintenance) that the scope of color variables is limited to config loading and show the right way to avoid further varible pollution (#28).
