New argument

• CollectionVariableArgument - expects an existing Collection variable

7 new methods

• CollectionInsert - inserts a value into a collection if of same type
• CollectionRemoveAt - removes the value at the given index
• CollectionRemove - removes the given amount of value matches or every match
• EmptyCollection - returns an empty collection of the given type
• JoinCollections - joins the given collections into one
• SubtractCollections - subtracts collections (removes a value from the first given collection if the value appears in the second or latter collection)
• SetIntercomText - sets the text on the Intercom Display (in the room in the Entrance Zone)

Method changes

• Moved AmountOf from the PlayerMethods folder to the PlayerVariableMethods folder
• Added a textOverride option to IntercomInfo which returns the text set by SetIntercomText

2 fixes

• Fixed JoinPlayers expecting List<Player> instead of Player[]
• Fixed and remade the comparing system on all of the value classes leaving just the global Equals method override and the == and != operators (all only in the Value class)
