NSS Kerberos' / Deltastation's Holodeck Glassification

[leboucliervert]

What Does This PR Do

• Replaces deltastation's holodeck's walls with reinforced glass windows and grilles in order to offer a full view of the holodeck to the spectators.
• Adds lattice between the reinforced glass station-side.
• Adds an extra row of chairs in the center of the holodeck's front.
• Removes the two walls next to the holodeck control's room.
• Replaces the light tubes lights that would be fixed to reinforced windows with floor lights.
• Adds a floorlight between the boxing ring and pool so that it is not too dark due to the removal of the holodeck's light tubes lights facing towards the fitness room.
• Removed a chair from the boxing ring's south row so it did not hide the floor light.

Why It's Good For The Game

Testing

• Loaded the map, went to the holodeck, confirmed I did not accidentally make the holodeck or fitness room spaced round start.
• Confirmed the lights were on.
• Squinted really hard to see if github hid a mapping conflict from me again, did not see anything about it being the case.

Declaration

• [x] I confirm that I either do not require pre-approval for this PR, or I have obtained such approval and have included a screenshot to demonstrate this below.
