Ehsan Akhgari 5cccea6f0f Bug 1145631 - Part 1: Replace MOZ_OVERRIDE and MOZ_FINAL with override and final in the tree; r=froydnj
This patch was automatically generated using the following script:

function convert() {
echo "Converting $1 to $2..."
find . \
       ! -wholename "*/.git*" \
       ! -wholename "obj-ff-dbg*" \
         -type f \

         -o -iname "*.mm" \) | \
    xargs -n 1 sed -i -e "s/\b$1\b/$2/g"
}

convert MOZ_OVERRIDE override
convert MOZ_FINAL final
