Make tunnel channel clients key-able. Neighbour map simplified. 
tunClient is a map of tunnel clients keyed on tunnel channel name.
Neighbour map is now a cimple map of nodes which contains its nodes.

Router cleanup and refactoring for win and profit. 
This commit adds the following changes to router package:
* it refactors Advertise() function which now does only what
it claims to do: advertising
* various router packages functions/methods have been renamed to make
their functionality more obvious and more in line with what they actually do
* function documentation changes related to the above bullet points

Renaming rampage 
Addressing the comments in #591, router.String() now returns "default"

Furthermore, a tonne of other renaming has been included in this commit
as a result of running go vet ./... inside the router package.

Fixes advert dampening behaviour. 
This commit adds the following changes:
* advert now stores a list of route events as opposed to just last one
* attempt to dedup route events before appending them to advert
* have max suppress threshold for long time suppressed adverts
* decaying events on every advert tick

Originally we werent decaying penalties on every advert tick.
That was incorrect behaviour. Furthermore some events would end up being
accumulated potentially causing memory leaks.

We were also overriding the last received router event which was causing
incorrect sequence of events to be applied when received by a receiver:
Create, Delete would be "squashed" into Delete only which would be
nonsensical since the Create event would never be delivered hence we
would be deleting nonexistent routes.

Not Decaying the events on every tick or not having the max suppression
threshold could lead to DoS by growing the router memory infinitely.

Router routing table management. Table route hashes. Status codes changed. 
We now manage routing table actions using dedicated functions run on
either registry or services in the registry.

Routing table now uses Route.Hash() instead of maintaining its own hash
struct filed which previously performed these operations.

Various names of variables have been changed to make them more concise.
