Further improved building placement failure check

Browse Source 
Since naval structures have their own safety measures now and therefore shouldn't count towards failCount under normal circumstances, we can now assume that 3 consecutive placement failures mean lack of space. Therefore, rather than unconditionally resetting the failCount and retry every N ticks, we now cache the number of buildings and construction yards at the time of the 3rd consecutive failure and if the number of buildings hasn't decreased and number of construction yards not increased, we assume there is still not enough space and reset the retry delay instead.
