Update to two packages in the collection:
pdftexcmds : add support for MD5 sum commands in XeTeX
(using new primitives added to XeTeX last year)
accsupp : support for Luatex added (separate from pdftex option,
so the luatex85 compatibility package no longer required)

fix test for etec.src for issue #33 (iflang)
Skip patching with newer graphics (fixes#29) (grffile)
