* macro 'alias' was renamed to 'rename'
* fixed `cargo test` on main project
The latter pointed me to the serde issue, which would have made
everything fail when actually used to communicate with google servers.
* keywords are no longer than 20 characters, which is a restriction
cargo imposes
* don't use 'homepage' link in cargo.toml unless the homepage is
non-empty
* Added all publish-results to mark the respective crate version

Previously, it would query the size from the wrong dict and obtain
the value 0 all the time. This would have made every upload fail with
`UploadSizeLimitExeeded`.
Now we obtain the actual size limit, and will ignore it if unset/0
for some reason.
