v3.0 with LuaLaTeX support and more

NB This modernises this package with LuaLaTeX support. While this change is highly recommended and in line with the development of LaTeX3 itself, for older packages that need pdflatex support continue using v2 instead.

• LuaLaTeX support (recommended---XeLaTeX does not support microtype yet)
• Breaks pdflatex support (for older documents use v2 but for everything else LuaLaTeX is recommended)
• Switched to OTF support with kpfonts-otf replacing kpfonts (addresses #9)
• pdfinfo incorporated into hyperref (addresses #10)
• Removed support for inputenc and fontenc due to LuaLaTeX (also addresses #10)
• Bug fixes (issue #5 persists but using \cleardoublepage manually works)
