Headers and profiler are now optional. Convenience methods for specifying a String URL or an
HttpClient directly are also provided.

Remove support for implicit injection.

Hide implementation detail UiCallback class in package scope.

Remove `Fetcher`.

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.

Now located at https://github.com/square/seismic.

Bump to 0.7.0-SNAPSHOT.

* Reintroduce shake detection as its own module.
* Move YAFFS-specific directory sync to its own module.
* Focus HTTP and I/O modules.
* Queue module for `QueueFile` and future queue-related stuff.

Eliminate 'android' module.

* Move `AndroidMainThread` to 'http' module. The Android dependency is marked as optional (though it is already provided scope).
* Remove `ShakeDetector` as it is not topical for this library.

More FEST-isms.

Re-enable 'android' and 'io' tests. Switch to FEST.

Eliminate barren 'core' module. Updates to other modules.

Move QueueFile to 'io' package.
