Describe the bug

(from discussion in telegram channel)
The sol macro using an abi file. The sol macro seems to automatically add #[derive(Clone)] to SolStructs and errors, but not to SolEvents, so trying to derive Clone when using an abi as input breaks because of conflicting implementations of Clone on SolStructs and errors.

[prestwich]

quickest resolution would be to add a clone derive to the code in expand/event.rs

[erikreppel]

@prestwich not sure if its just this easy #616

[prestwich]

yeah, that should do it. we need to release cc @DaniPopes

this is technically a breaking change but given the nature of the issue, basically no one would've actually hand implemented clone for these things

[prestwich]

As follow up, we should probably make sure that we're completely consistent across all generated types

Fix released in 0.7.2.
