Firmware upgrade: 1.20

[Vectrex32]

There's a new version of the Vectrex32 firmware available, version 1.20. This adds several new features as well as dramatically speeding up BASIC execution:

• Add C-like structs
• Add matrix arithmetic: +, -, * (dot product) and / (by a scalar)
• Add matrix functions: norm(), transpose(), cross() (for cross product)
• Add ByRef keyword to specify when arguments should be passed to subroutines and functions by reference instead of by value.
• Add atan2() function.
• Add DeepCopy() function for copying arrays and structs

If you already own Vectrex 1.10 or newer, you can download the firmware here. If you still have version 1.00, please read this.
