Remove usage of jollyday.properties file

[svendiedrichsen]

Replace the usage and loading of implementation classes from properties file with default impl instantiation from code.

Maybe I take this one, one idea would be to have a factory method on the Enum so that each HolidayParameter is instantiated using the such factory method.

WDYT?

[svendiedrichsen]

I thought of getting rid of the instantiation by reading the class names from the properties file and having the Parameter class contain instances of the default impl classes. They may be overriden by using setters passing in new implementations.
Where and when to create the default impl instances I haven't thought of yet but they should be returned from the HolidayParameter instance.

I'll take a look sometime around the weekend, my idea is to completely avoid reflection and just use some factory function, I'm thinking to add such factory function to HolidayCalendar Enum, so each Enum will require a factory function from which it will create everything it needs without needing reflection.

[svendiedrichsen]

Sounds interesting. Looking forward to it.

I'm trying to make the code compile on IntelliJ and outside using Maven directly but I'm getting the following error:

Ignore the previous comment, the issue was related to Java 9, as soon as I pointed the project to Java 8 everything worked.
