Map Fixes and Engine Rebuild

-Fixed pipes in Miscellaneous Research and Telescience being replaced by
Bio Hoods
-Removed extraneous large vent from Bar
-Added camera to atmospherics substation near security to allow AI
ability to turn on emergency supply

Complete Engine Rebuild:
-Added missing windows to core containment
-Altered default loop to prevent explosion if engine is not set up
-Removed excess emitters
-Restored gas composition values to sensor in core
-Replaced monitoring computer with one more suited to the task
-Added additional gas filter to allow for nitrogen-only return to the
core. Other gases must be sent through the bypass pump to the left of
the filter
-Added engineering access to filters. Previously, there was no access
restriction, meaning anyone who gained entry to the core could alter the
filter settings.
-Added pump to nitrogen entry port to allow more rapid and complete
draining of linked nitrogen canisters
-Added pumps to waste gas (oxygen, nitrogen, and other canisters) outlet
ports for greater safety if large quantities are being removed from the
engine
-Added lines, vent, and scrubber to provide normal atmospherics to
non-core area of engine room.
-Added lines, vent, scrubber, and air alarm to engineering storage. This
was important, as this room is the most likely room in all of
engineering to have a plasma spill.
