Change checkParameters() error messages to always give name of function

[Merudo]

• Change wrong number of parameters error messages to always display name of function
• checkParameters method in AbstractFunction changed to take functionName as first argument
• Need to do: change every checkParameters(parameters) in Maptool project to checkParameters(functionName, parameters)
• Parser changes to close Change parser to provide more helpful error messages for incorrect # of parameters #2
• New error message for math functions. For example, for Floor(),

Old error message:

Invalid number of parameters 0, expected exactly 1 parameter(s)

New error message:

Function 'Floor' requires exactly 1 parameters; 0 were provided.

need to update so that the error messages are internationalized. I realise its another painful dependency but its equally if not more so painful for anyone developing macros with MapTool in a different language if they get an error they can't understand.

I am open to other options if this is too painful (such as creating a utility class for macros in MapTool and changing functions to call that, I am pretty sure if we made such a utility class we could find other common macro code that could be moved to it as well).

Current error message are also not internationalised so I will approve and open another issue for internationalisation of this project.
