Implementation of the Preference Panel

[saulhidalgoaular]

Saul POS requires to have a preference panel. Currently, it is being stored into the bean Configuration, handled by the Crud. However, it should be more user friendly.

I suggest the integration of the PreferencesFX into the project.

Adding some default configuration as example. Later during the project, more parameters will be added on the way.

Suggested parameters to add into the preference section: Company Name, Logo, Date Format, Currency Format, Password Lock time, Minimum Initial Money in Cash, Images Path, Enable Search by Product, Enable Sales without Stock, etc
