This modifies update_files to update each tor browser binary in gitlab,
internet archive, and google docs, and then delete the binary before
downloading the next one. This will save storage space on the gettor
host.

Delete unused scripts

This script had important commands for updating internet archine and
google docs. The github release script has been renamed to
update_github.

Have the script read directly from an environment variable instead of
passing the token in as a command line argument. This will hide it from
other processes.

Also removed downloaded files to prevent a messy directory.

- also fixed a bug where releases won't be deleted untless the assets
are removed first

The script will continue with the rest of the uploads but will exit with
a non-zero code so that we'll be notified to upload the missing files
manually.

We were running out of space in both of our github and gitlab
repositories due to storage limits. This change switches to using the
github REST API to upload torbrowser binaries as releases. Releases are
not subject to the space limits of repositories and, even better, do not
count against our bandwidth limits when users download them.
