Fixed spelling on downlaods -> downloads.
Thanks for notifying this typo. I know this is a trivial change but since Byteman is a JBoss project I am not able to accept pull requests from someone who has not signed a JBoss contributor agreement for Byteman. If you think you might want to contribute code to Byteman in the future then you are welcome to obtain a jboss org account and sign the contributor agreement at https://cla.jboss.org/. Meanwhile I will fix this typo in my repo and push it up to the master.
