Updates to the Wii/GC versions of the 240p Test Suite

Here's version 1.19 of the 240p test Suite for Wii and Gamecube

- Added Disappearing Logo test: This test helps to measure display and controller lag, via photo-diode and/or with slow motion cameras.

- Added Phase & Video Sample Rate test: This test was developed thanks to the input and design from FirebrandX. It helps to dial in upscaler phase, like for example from the RetroTink 4K

- Added the side bars and color toggle to the Lag test: This test was designed to measure lag, and with the added features it helps to visualize in slow motion or capture devices, since frames have complementary colors. It can also be used with fields in 480i video, with each field having a unique number.

- Updated Monoscope by Keith Raney: Symmetrical improvements he found recently.

- Improved MDFourier: It now it works perfectly on Game Cube & moved it to AESND, thanks to Extrems. Also added online help and improved the interface to use it.
