Isolate classes from Base to separate files

[alisnic]

I was looking at Sinatra source code, and tried to understand how it works. The first thing I noticed was "there's SO MUCH STUFF in base.rb", seriously it's pretty easy to get lost there.

I isolated some of the classes from base to separate files up to the point when it would require to fiddle with the project object hierarchy to proceed. base.rb has shrunk with ~800 LOC.

This is my first attempt at a open source contribution like this, so I will understand if you will consider my efforts pointless.

Edit: The Travis build is failing, but it's not related to my changes as I see it. The errors that Travis throws are related to failure to get a gem, but I didn't touch the Gemfile. rake spec gives no failures for my changes.

As @rkh said, there are no plans for this until 2.0.

See #658.

@patriciomacadden, Is there anything else I can do to help the project on this one? Or the idea is to just wait for 2.0 and then proceed?

[patriciomacadden]

I think that there are no plans for 2.0 yet.

[patriciomacadden]

You could help on sinatra-contrib or sinatra-recipes.

@patriciomacadden thanks, I will look at the projects.

There's no point in keeping this PR open, right?

[patriciomacadden]

No, but thanks anyway for your time!
