Bugfixing more pages in Framework_MCM

- MCM script: renamed ModName to NameOfMod (ModName is already a
property defined in SkyUI, leading to errors). Any functions using this
were also renamed for uniformity.
- GO in InitManager now becomes disabled when nothing to initialize.
- Fixed logic that converts SyncMode from Int to String (it was using ==
instead of =).
- Renamed any j variables (when used as counters in WHILE loops) to i
for readability.
- Deleted debugging lines.
- New translated string: $PLEASE_SELECT_NPC_FIRST.
