[1.3.b59] macro function to return num of entries in table

[Azhrei]

Easy one: add a macro function (perhaps getTableData()) that returns the number of entries in the table.

The reason the function name is rather generic is to allow this function to take a parameter that specifies what kind of data to return. Possible return values include number of table entries, picture used to represent the table (in the table panel), whether the table is player viewable, number of table entries with/without images/text, and possibly more. (I'm sure the developer who makes this change will see the Java object that represents a Table and have ideas for other attributes.)
