[Feature Request] %E Format specifier

[xerox8521]

I'm proposing a new specifier %E which takes an entity index which will insert the entity's classname. Similar how %N inserts the players name. If you have a better character suggestion I'm open to hear about it.

Which will make code like this

void Foo( int entity)
{
    char szClassName[32];
    GetEntityClassname(entity, szClassName, sizeof(szClassName));
    PrintToServer("ClassName: %s", szClassName);
}

be replaced with

void Foo( int entity)
{
    PrintToServer("ClassName: %E", entity);
}

I think having the entity name in there would be great, too. Similar format to ent_remove.
prop_dynamic(prop_resupply_red_2)
beam(beam)
