Change String to &str for all Rocket functions

During setting the latest commit hash for Rocket and updating all the
other crates, there were some messages regarding the usage of `String`
for the Rocket endpoint function calls. I acted upon this message and
changed all `String` types to `&str` and modified the code where needed.

This ended up in less alloc calls, and probably also a bit less memory usage.

- Updated all the crates and commit hashes
- Modified all `String` to `&str` where applicable
