Use the default locale when initializing SimpleDateFormat.

Specifying a custom locale causes a considerable slowdown on Android.
Better fix for TFJ-619, support current_user_retweet field in Status object
Fix bug with SimpleDateFormat when the default locale is not US.
Use UTC instead of GMT.
Fix issue - control stream not being renewed upon stream reconnect

**The issue:**
If we have a stream that is connected, and then a disconnect and reconnect occurs,
the control stream URI does not get updated correctly.

This is the error message that occurs on a reconnect:
```
15:32:30.196 [Twitter4J Async Dispatcher[0]] ERROR t.internal.async.ExecuteThread - Got an exception while running a task:
java.lang.StringIndexOutOfBoundsException: String index out of range: -15
     at java.lang.String.substring(String.java:1937) ~[na:1.6.0_31]
     at twitter4j.SiteStreamsImpl.parseLine(SiteStreamsImpl.java:76) ~[twitter4j-stream-3.0.0-SNAPSHOT.jar:3.0.0-SNAPSHOT]
     at twitter4j.AbstractStreamImplementation$1.run(AbstractStreamImplementation.java:93) ~[twitter4j-stream-3.0.0-SNAPSHOT.jar:3.0.0-SNAPSHOT]
     at twitter4j.internal.async.ExecuteThread.run(DispatcherImpl.java:116) ~[twitter4j-core-3.0.0-SNAPSHOT.jar:3.0.0-SNAPSHOT]
```

As a result, any further control stream commands result in a 404.

**To reproduce:**
Start a site stream connection and wait until it is active.  Now cause a disconnect (perhaps turn off WiFi),
and wait until Twitter4J detects the disconnect and does a retry.  Now make sure connection is active
(turn on WiFi) and you should see error above when a control stream is issued by twitter.

**The cause:**
This happens because on line 59 of `SiteStreamsImpl` there is a check `cs.getControlURI() == null`.
Since the control URI has been set by previous connection, it does not pick up the new control URI.

**The fix:**
There are a few ways to fix this.

* (THIS PR) - in `public void next(StreamListener[] listeners)` detect if an exception has been thrown
that causes a disconnect.  Set the control URI to null in this case.  Note that there is probably a better
way to detect a disconnect than checking exception message, but the variable `streamAlive` in
`AbstractStreamImplementation` is private and cannot be accessed from SiteStreamImpl.

* The other way is to remove the check `cs.getControlURI() == null &&` on line 59 of `SiteStreamsImpl`.
