Merge pull request #1 from phi-gamma/master

Updating with current master
add link to dev repo
set minimum luatex version to 0.76; reduce verbosity of fontdbutil
Import from Context as of 2013-04-23

Added: font-opt.lua.

This breaks anum.tex / loading the amiri font.
update basics-gen.lua
eliminate loop in db updater
add “both” directive for logger
pick path normalizer only once per run
collect stats about new additions
catch irregular ``file:`` lookups

we now index base names and extensionless base names of font files as
well so as to work around quirks of the Xetex compatibility layer.

this will probably get removed after the syntax parser is redone.
import from Context as of `date`
make db reloading require a reason; decrease nesting depth of conditionals
default to “node” mode processor again
