Restore Gson 2.2.3-SNAPSHOT, which now supports serialization.

Serialization fix in Gson is here:
http://code.google.com/p/google-gson/source/detail?r=1177

Roll back gson change: it breaks serialization

Update Gson to 2.2.3-SNAPSHOT.

Adding a human-readable name to the Server interface

Support JSR-330 instead of Guice.

This change is *extremely* backwards and forwards incompatible
because it replaces Guice's @Named with JSR-330's @Named.
Programs that use the wrong @Named will not work at all. For
this reason it's critical that clients of retrofit also change
their @Named in sync with this update.

Make RestAdapter work with JSR-330 injectors other than Guice.

Conflicts:
	http/src/main/java/retrofit/http/RestAdapter.java

It still depends on Guice and works on Guice. But this baby step
will make it easier to use RestAdapter on another injector.

ANDROID-3631: PUTs don't have a content-type, don't NPE on them

Temporarily roll back to GSON 2.1.

Adding a beforeCall() to HttpProfiler.

Adding a beforeCall() to HttpProfiler. Allows profilers to track data that may change over the course of the server call.

Upgrade to Gson 2.2

The main benefit of this update is that it fixes a DoS vulnerability.
The benefit I'm interested in TypeAdapter.toJsonTree and fromJsonTree.

Introduces MainThread#executeOnMain.
