Changed the timoeut of EQ 502s (no events) to 50 secs. The viewer post requests timeout in 60 secs.
...
There's plenty of room for improvement in handling the EQs. Some other time...

Do some simple queue empty checks in the main outgoing udp loop instead of always performing these on a separate fired thread.
...
This appears to improve cpu usage since launching a new thread is more expensive than performing a small amount of inline logic.
However, needs testing at scale.

Cleared up much confusion in PollServiceRequestManager. Here's the history:
...
When Melanie added the web fetch inventory throttle to core, she made the long poll requests (EQs) effectively be handled on an active loop. All those requests, if they existed, were being constantly dequeued, checked for events (which most often they didn't have), and requeued again. This was an active loop thread on a 100ms cycle!
This fixes the issue. Now the inventory requests, if they aren't ready to be served, are placed directly back in the queue, but the long poll requests aren't placed there until there are events ready to be sent or timeout has been reached.
This puts the LongPollServiceWatcherThread back to 1sec cycle, as it was before.

Attachments module only registers when enabled. This enables alternative attachments module implementations. All calls to Scene.AttachmentsModule are checking for null. Ideally, if we support disabling attachments then we need a null attachments module to register with the scene.

In the pursuit of using less CPU: now trying to avoid blocking queues altogether. Instead, this uses a timer. No sure if it's better or worse, but worth the try.

This adds explicit cap poll handler supporting to the Caps classes rather than relying on callers to do the complicated coding.
Other refactoring was required to get logic into the right places to support this.
