Closes #65

Abstract HTTP entity (de)serializaton to converters.

This allows for specifying different serializations formats for
use over the wire.

This commit also lays the groundwork for future synchronous invocation.

Remove erroneous javadoc.

Use ServerError directly in sessionExpired and serverError.

This is a short step on the road to HTTP body format agnostic support. And it's
not a pretty step, either.

Allows spaces to appear in path parameters.

Purge QueueFile.

It now lives on its own in http://github.com/square/tape/

Remove web URL and ignore SSL boolean from Server.

These do not belong here.
