Similar renaming for Font::loadFromMemory and Font::loadFromStream.
The goal is to better express the need to keep the source available,
similar to Music::openFromFile for example.
By deleting this constructor overload, it fails to compile if
you pass a temporary font to this parameter slot. That includes
code like
sf::Text text("", sf::Font());
but more importantly it prohibits code like this
sf::Font getFont()
{
sf::Font font;
// load a font...
return font;
}
sf::Text text("", getFont());
The same idea can be applied to setFont() to prevent setting fonts
from a temporary.
