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.
Moved all personal scripts to ~/.local/bin to be systemd file hierarchy
compliant, as well as XDG compliant. Since they are not configuration
options they don't have anything to do in .config directories.
Also, it's just easier to find than the previous .config/scripts/bin.
