hoarders - refactor code to check hoarder level and upgrade when energy is available

[CobyR]

since hoarders are vital to a constant stream of new energy, if they are spawned during a low energy period they are less effective.

add code to check energy levels and the level of the hoarder, if there is room to build a 3 or above (they are all the same at that point) then exceed maximum and spawn a H3, then once H3 is alive, suicide the summoner.

See Secret room code for previousrole creeps as an example of tracking creep making request for improved Hoarder and then the execution of summoner
