Library and demo now work with newest rust and dependencies.
I've also gotten rid of all warning messages, usually by replacing the deprecated code. Sometimes not though: I've added a dependency to c_vec because otherwise large parts of imagefilter.rs would need work -- CVec has been removed from the std lib.
Details in commit messages.
Hopefully I didn't break anything. I could not test everything and mostly relied on the compiler.
