Improved error handling

[markguinn]

At this stage, error handling is largely silent such that if there's an upload or download error it just serves from the local assets as much as possible.

I'd like to see this taken up a notch:

• Turn on logging via Monolog with fallback to Debug::log
• Should be able to crash on error in some contexts (like possibly a build task)
• Configurable via yml

Hi Mark!

What's the status for this. I can't seem to get the module to work and want to find out why it doesn't

Can you provide some sort of test build task to see if it can connect properly to the S3 server?

Thanks.

To be honest, this project is not getting much love and probably won't. Silverstripe 4.0 will make it unnecessary and we're not using it on any new projects. I'll happily merge pull requests but I don't have much time to give it. If you're using SS3.2 I think there are some known issues.
