Make Grape::Exceptions full_messages public

[romanlehnert]

Grape::Exceptions::ValidationErrors#message currently joins the error messages together. Example:

"id is missing, name is missing"

However, when building custom error responses, that handle each single validation error separately, Grape::Exceptions::ValidationErrors#full_messages is extremely useful:

["id is missing", "name is missing"]

But this method is private. So my questions are

• What do you think about making this method public?
• Or is there a better way to access the single validation error messages?

Thanks!

I don't see a problem with making this method public. Write a spec for it and make a PR.

I'll do that. thanks.
