alias copy_machine -> photocopier

create alias copy_machine -> photocopier

Photocopier is the common term for it. It was aliased to copy_machine in forum #122610 without much discussion because copier was already aliased to copy_machine, which doesn't seem like very good reasoning.

This seems like another America-vs-the-world situation. Copy machine is more common in the U.S. by a huge margin whereas photocopier is preferred in the rest of the English-speaking world. Source: Google Trends.

Photocopier is faster to tag since there are no spaces. Copy machine is verbose and not the proper term, so I wonder why this alias doesn't exist yet.
