This additionally:
* Makes all copyright notices identical aside from the starting year for Wesnoth-specific source files. Files not included: mariadbpp, lua, spirit po, xbrz, and bcrypt (crypt_blowfish).
* Removes all attribution from the files, since the vast majority of them are outdated or seemingly just outright incorrect. For example, I would guess that Dave is no longer the sole author of the majority of Wesnoth's current code.
Covers more cases of:
* push_back(std::pair
* push_back(std::make_pair
* push_back(std::make_tuple
* push_back(T) where T is an empty object of type T
Small thing I noticed: this does mean the numbers in font::subset_descriptor are no longer 'cast' to size_t before being
added to the vector, but that shouldn't matter (hopefully).
It is now possible to write multiple config objects in a single package,
the server reads them then as one big config. Prevoulsy if people wanted
to do that they had to copy both configs into a new config which is
slow, specially if those configs are very big becasue they contain a
whole scenario or an era.
