The reason for this is that we might be able to overwrite mate even if we do not have write access to the parent directory. This will avoid us having to prompt the user for an admin password (when updating mate).
It should be mentioned though that incase mate is not a regular file, we do need to remove it first, because if e.g. it is a symbolic link, our install would write to where the link points to.
Previously we installed this from the Bundle Support bundle’s support path.
While the Bundle Support bundle is a requirement to work with TextMate, including mate in the resources section should ensure we always get the latest build and address issue 53.
