Convert favorites list to functions list

[daniellimws]

A more practical usage of the favorites list is to have user-defined functions, since that was the intended use anyways.

To do this, best to do the following:

• Create FunctionBlock
• Export functions to script
• Allow users to define function name on function
• Need to figure out a way to pass in parameters
• Need to figure out a way to define return value

Most likely merely a list block ain't gonna do the work, spawning a dialog box to customize function specifics would be more helpful.
