configuration for a subject prefix for email

[francescob]

Added an option to add a subject prefix to the emails sent by solid_errors. Useful when you have multiple apps/environments using solid errors and what to easily filter the email received

I like the idea, just one small change needed

Ok, now the empty prefix is handled.
i also have another idea that fits in the way we use solid_errors:
Make subject_prefix enabled by default, with a value of
[#{Rails.application.name.upcase][#Rails.application.env.upcase].
Disable it with config.solid_errors.subject_prefix = "" or override it with your own custom string
What do you think about that?

LGTM

Making this the default would be a breaking change. I would rather introduce such a change slowly. So, let's start by providing that as the example in the README for this feature.

Ok i've renamed the option for conformity with other email settings and updated the README

Just a few changes, then should be ready to go

Lovely! Thank you for this
