77 Rust Crates, fluid, roboto-font, libpsyc rust bindings

[ng0]

... and I still am not sure wether the build system works or not (see bottom of 
this email) because I still have to learn more about this language. Our 
prototype will soon switch to fluid (it's currently using qml-material but I 
refrained from adding that as its upstream looks like it moved on to fluid), so 
apart from the prototype the only "real" application I can check this chain on 
can only be added later after this has been added. Remember panopticon, the 
package which got me to poke at the rust/cargo in winter of 2015 and spring of 
last year? This can be made functional (finally) once I package some more 
crates in addition to all the ones I send with this.

Please provide constructive critique and review. Read the crate repositories 
and their own descriptions etc. It was very hard and not intentional to end up 
with tautological descriptions/synopsis. Remember that we are starting at zero 
and that some (most?) of the now following crates add very basic 
functionalities.

[PATCH 81/86] gnu: rust-docopt: Add rust-regex input.
[PATCH 82/86] gnu: rust-quickcheck: Add rust-env-logger input.

Add those just now because those are dev-inputs or otherwise not needed for 
functional "build".

[PATCH 83/86] gnu: Add fluid.
[PATCH 84/86] gnu: Add libpsyc-rust.

I would need to run 2 build-systems here in libpsyc. Advice needed in how to 
achieve that. You can also provide me with good points why (if at all) this is 
a bad practice (all bindings in one distribution) and we should move rust 
bindings to its own package.

[PATCH 85/86] gnu: libpsyc: Remove comment.
[PATCH 86/86] gnu: Add font-google-roboto.



I have not run any of the 81 packages through guix lint, I would if I would 
know a way to mass lint a list of packages.
For those I checked (like rust-openssl-sys) left me in confusion. Does our 
cargo build-system just build nothing? Are all of these libraries? 
rust-openssl-sys contained nothing, but rust-openssl-sys:src had all the data. 
Same goes for the libpsyc-rust
