Implement Error Checker

[Daniel7Sly]

Error-Checker

The Error Checker will search for errors in the entire script before the execution of the script.
Since the way ABIS is build this can be acomplished and make ABIS free of Runtime Exeptions.

The Error-Checker should look for:

• invalid variable names.
• validate types in parameters actions.
• action names and parameters quantity.
• validate Blocks names, input & output types.
• invalid Flag names/refences.
