Ehsan Akhgari 883849ee32 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..."

}

convert MOZ_OVERRIDE override
convert MOZ_FINAL final
