Paths filter

[pablobm]

I wanted to put my site on maintenance mode, but still have access to the admin interface. This pull request makes this possible.

Please note that I update Gemfile.lock, which looks like should have been updated on master, but wasn't. Is this correct?

@iainbeeston what exactly, is shocking?

[pablobm]

@tilsammans Don't worry, he works with me and was joking. It's a reference to the title of the last commit. (In fact it's a comment on that commit specifically).

And I'd be shocked and appalled if I was him too!

[tilsammans]

@iainbeeston never mind, read your comment out of context ;)

Taking a look at this now!

Sorry for the confusion!

[tilsammans]

Thanks for the contribution! I've opted to drop the built-in /assets filtering and leave everything in the hands of users. Any paths to be bypassed can be added to the new without option.

Since this breaks previous behaviour, I've released version 2.0.0 which will print a post-install message.
