Invalid file permissions for sdluatex in distros

[zopyx]

MacBookAirAndreas:examples ajung$ sp
Run speedata publisher
fork/exec /opt/speedata-publisher/sdluatex/sdluatex: permission denied

At least Mac and Linux distros contain the sdluatex binary without +x flag set.

speedata-publisher-linux-amd64-2.6.0.zip - confirmed
speedata-publisher-linux-386-2.6.0.zip - confirmed
speedata-publisher-darwin-amd64-2.6.0.zip - confirmed

so the rest is probably broken as well... This is not good...
