- rearranged code to reduce cyclic dependencies
- doCleanShutdown is separated in shutdown.py
- shared queues are separated in queues.py
- some default values were moved to defaults.py
- knownnodes partially moved to knownnodes.py
Commit 5b23d9 removed the line "import shared" from helper_inbox. Almost
all of what shared was used for became covered by helper_sql. But, shared
still needs to be imported because there is still one line that uses
shared:
9: shared.UISignalQueue.put(('removeInboxRowByMsgid',msgid))
