Big update to look and feel of entire episode 1!

• Campaign mode: tweak pacing and level design, shotgun may now be obtained on level 3

• Arcade mode: shotgun may now be given by rng god earlier than level 4

• Special Rooms
  • Special Room's voxel map may now spawn rotated making level  more random
  • Add new special rooms
  • Remaster old rooms
• Remaster room links:
  • Room links / connections / doorways (however you want to call it) now have procedural size and offset, making levels more open
  • Links in outdoor maps now don't have silly link ceiling
  • Add more variations of locked doors (size)
• Outdoor map rooms now have correct wall size in relation to neighbors

• Add, procedural 'doors' to doorways to hide ugly room loading (and somehow help indicate maze direction?)

• Tweak AI processing

• Minor bugfixes / tweaks
  • Fix dialog to pickup powerup not appearing when player opens treasure chest by hand
  • Enemies spawned dynamically (during boss) autonomically free their slots, allowing boss to spawn more enemies again
  • Enemies: fix walking animation not triggering when loosing line-of-sight to player
  • Rename option "Legacy Campaign Generation" -> "Do not randomize campaign seed" to avoid confusion
  • Update some wording in manual
• Difficulty tweaks:
  •  "Arena" rooms have 1.5x base difficulty because they're more open by nature
  • Enemy projectiles have more lifetime before de-spawning
  • "Chaser" moves a little faster
  • "Big B." will not attempt to shoot hurting and spawner projectile at same time (so less friendly fire)
