fix maxspidersperip limitation not being obeyed.
removed fakedb.
only add "0" time waiting tree keys to waiting tree.
only scanSpiderdb() will change their times to
a future time or add them to doledb directly.
confirmLockAcquisition() will not add to waitingtree
if max spiders per ip limit would be exceeded.
an incoming spider reply will trigger the add to
waiting tree with a time of "0".
as far as adding/deleting/resetting colls
and updating parms. ideally we'd have a Colldb
Rdb where each key was a parm. that would make
syncing easier if a host went down, then it would
get the negative/positive colldb parm keys later.
so it could sync up on all your operations as long
as all your operations in terms of adding and deleting
database key/value pairs.
