Fix Interval Map GetAlignedRecursiveRange lookup bug

Browse Source 
Any lookups done using `GetAlignedRecursiveRange` incorrectly added intervals in the exclusive interval entry lookups as the condition for adding them was the reverse of what it should've been due to a last minute refactor, it led to graphical glitches and crashes. This has been fixed and the lookups should return the correct results.
