PCA Server Manager 0.1.3

• New: /studentmode. A teacher's own account acts like a student's until they turn it off, to see what children see: no op, no PCA Classroom or PCA Perms teacher powers (so /class freeze and mute work on them), survival mode, and this mod treats them as a student. /studentmode off puts it all back exactly as it was (op level, Classroom teacher list, PCA Perms groups, game mode), even after a server restart. Permission: pcaservermanager.studentmode (ops by default).
• Logs and messages sent to the portal say "student_mode": true while a staff member is acting as a student.
