BSD License and GPL source file headers conflict

[juhp]

1f4e239 changed the license to BSD however the source headers still say GPL:

./Text/Pandoc/JSON.hs:23:   License     : GNU GPL, version 2 or above
./Text/Pandoc/Definition.hs:24:   License     : GNU GPL, version 2 or above
./Text/Pandoc/Builder.hs:25:   License     : GNU GPL, version 2 or above
./Text/Pandoc/Walk.hs:29:   License     : GNU GPL, version 2 or above
./Text/Pandoc/Generic.hs:22:   License     : GNU GPL, version 2 or above

Could you please update them?
