Request: remove hard-wrapping of tex files

[luciansmith]

Deviser output writes tex files (particularly the validation appendix) and hard-wraps the lines at 80 characters. This makes it difficult to run search-and-replace functions, which are particularly necessary when dealing with non-SBML specifications, but can also be a pain for normal SBML package specifications. If hard wrapping was removed, it would make dealing with these files easier.
