Fix pdf compilation targets and Library envvar

Pdfs will be compiled, replacing special characters with underscores;
this fix also looks for underscored files when trying to open the
compiled version of a file.

The Library environment variable (for my default bibtex library
directory) overwrote yay's library directory; it has been renamed to
LIBRARYROOT to both mirror WIKIROOT as my note directory and keep the
LIBRARY variable empty so yay will continue working.
