Add arXiv target to Makefile

[matthewfeickert]

The arXiv target prepares a tar.gz file with all the necessary files for arXiv to build the document correctly.

Hi @matthewfeickert

When you compile the latex code, in the directory is generated a file main.bbl that is required to arxiv, is just to add this to the compressed file.

[matthewfeickert]

@omazapa Yeah, I guess we just had perfect timing and figured this out about the same time. I'm commiting a Makefile (commit b9607f7c281d591ea18bd136b854a7cb4dce84bd) that moves this in as ms.bbl. :+1:

HI @matthewfeickert ms.tex is the main.tex? because it works for me with main.tex and main.bbl Thank you!

@omazapa arXiv gives priority to ms.*, so this is just making things easier by explicitly renaming them in the tar.gz building step.
