raise bandwidthrate/bandwidthburst to a new "infinite"

addresses bug 6605.

changes/bug6605

+  o Major bugfixes:
+    - Raise the default BandwidthRate/BandwidthBurst values from 1MB/5MB
+      to 1GB/1GB. The previous defaults were intended to be "basically
+      infinite", but it turns out they're now limiting our 100mbit+
+      relays and bridges. Fixes bug 6605; bugfix on 0.2.0.10-alpha (the
+      last time we raised it).
