[FEATURE] `targetexists` expression for indicating target cursor reticle

[ncskrypt]

targetexists ['any'/'beneficial'/'harmful'/'neutral']

• Expression to indicate if you currently have a target cursor reticle
• Optionally specify beneficial harmful neutral, otherwise any can be assumed
• Provides similar functionality to waitfortarget [timeout] but as a boolean expression without waiting

Examples of Cursor Types

• beneficial : Greater Heal, Invisibility...
• harmful : Energy Bolt, Magic Arrow... (Unsure if Stealing is considered Harmful)
• neutral : Invite Party, Use Scissors, Telekinesis, Animal Lore, Explo Pot, Field Spells, Blade Spirits, Meteor Swarm, many others...
