Various fixes for LuaTeX compatibility
Add OFL

The Emmentaler fonts are licensed by the OFL
This allows to redistribute them without source code
Add dummy FONTLOG

The FONTLOG should contain information on the Emmentaler fonts
as described at http://scripts.sil.org/cms/scripts/page.php?item_id=OFL-FAQ_web#43cecb44

We should use it and supply that information
Fix \lilyglyphs for LuaLaTeX

LuaTeX preferred the sibling .png file over the .pdf logo image.
Fixed by explicitely including .pdf
.gitignore: add *.synctex.gz
Remove obsolete lilyglyphs_overview.tex
