+ New cache ipc handlers for adding server caches

Interface for this is fiddly and probably requires real docs to be further developed
without losing my mind doc the whole cache at some point
+ New cache ipc handlers for adding a new open web socket
Web socket comes with some basic listeners, however very litte/nothing
is being done check the health of these connections or to try when possible.

+ Cache now adds actual message objects to its message arrays instead of raw strings (wew)
+ Events module has been added to move the parsing logic/validation away from everything else

+ The basic Event structure has some niftier-than-you-think behavior for data acccess which the cache can leverage for more concise+ correct behavior
