Create version bump script

[drubin]

Simple script to replace the version of gitlab in all the files.
Works on osx and linux

This also rewrites the Changelog.md which is probably unintended.

I just clumsily did something similar while staging a version bump (which should be easy) but it is easily manually patched. Excuse my french:
for file in $(grep -r 10.3.3 . | cut -d: -f1 | sort | uniq); do sed -i 's/10.3.3/10.3.4/g' $file ;done

Thanks. Will fix it to exclude the changelog. But yes it should be easier. The annoying bit is also making it work both on mac and Linux.

FIxed to exclude the changelog.
