More configuration for historic event modules

[fisharebest]

We can pass additional parameters to the historic events modules, to allow them to decide which events to show.

For example, the page language, or the individual on the page.

[Manja-S]

Another example: the country (or countries in case of emigrants) where the individual lived (or lives).

Maybe its a good idea to group the historical facts by moving them into a subfolder, e.g. webtrees/app/Module/History or, as a alternativ, to start the name with e.g. HistoryCamelCaseName?

This is already available. The module has access to the individual, and so can easily examine the facts/places/countries.
