Title: Only warn on JS minification errors, and allow for custom minification ignores

My site has Greasemonkey scripts (.user.js) which don't compress via Uglifier, and some PHP that also won't compress with the inline-js stuff. So I added the ability to add extra ignore regexes, and made it warn on Uglifier errors rather than erroring.

Custom ignores work like this:

```ruby
activate :minify_javascript, :ignore => /\.user\./
```
