Rebuild Cache

Whenever a structural change to a station is made, by adding or removing a Component or History, invokes an action on the NHaystackService called rebuildCache. By invoking rebuildCache, it causes the NHaystack Server to traverse through the entire station and rebuild all of its internal data structures, so it can keep track of how everything in the station is interrelated.
