Include span label in rust lints (#601)
* Include span label in rust lints This turns relatively unhelpful error messages like mismatched types into more expressive messages along the lines of mismatched types: expected bool, found integral variable Fixes #597. * Exclude rust lint span label if empty * Use single-quoted strings in vimscript * Add test for detailed rust errors * Prune Cargo JSON * Use matching error file name * Byte offsets not char offsets
