modules/rkt: limit Rocket reconnect frequency to 2HZ
On Linux I don't notice a significant affect on anything letting
rkt try connect every frame when offline but in creative mode.
On Windows however, Dan reported significant latencies in the
Scener prompt responsiveness and visible slowdowns in this
condition.
I suspect the WIN32 Rocket library's sync_tcp_connect() code is
the real problem here. But for now I can ameliorate things a bit
by just hammering on that code path less when unconnected.
