Hotfix of IAA paper icon

Hotfix for a change is how the papers iconstate change was handled in https://github.com/d3athrow/vgstation13/blob/Bleeding-Edge/code/modules/paperwork/paper.dm

Didn't exhaustively test everything remotely related but it should be aight.

To clarify, currently the papers are invisible because the IAA papers are paper_words and the functionality of papers.dm was changed from if info set to papers_words to if info +_words
