* Analog TV app (PAL)

* Icon on main menu

* Analog TV should be yellow

Works for PAL only know, it would be nice to add NTSC in the future, or some customizable sync

//spectrum.db[i] is 256 long
//768x625 ->128x625 ->128x312 -> 128x104
//originally @6MHz sample rate, the PAL should be 768x625
//I reduced sample rate to 2MHz(3 times less samples), then calculate mag (effectively decimate by 2)
//the resolution is now changed to 128x625. The total decimation factor is 6, which changes how many samples in a line
//However 625 is too large for the screen, also interlaced scanning is harder to realize in portapack than normal computer.
//So I decided to simply drop half of the lines, once y is larger than 625/2=312.5 or 312, I recognize it as a new frame.
//then the resolution is changed to 128x312
//128x312 is now able to put into a 240x320 screen, but the buffer for a whole frame is 128x312=39936, which is too large
//according to my test, I can only make a buffer with a length of 13312 of type ui::Color. which is 1/3 of what I wanted.
//So now the resolution is changed to 128x104, the height is shrinked to 1/3 of the original height.
//I was expecting to see 1/3 height of original video.
//Look how nice is that! I am now able to meet the requirements of 1 and 3 for portapack. Also the length of a line is 128
//Each call back gives me 256 samples which is exactly 2 lines. What a coincidence!
//After some experiment, I did some improvements.
//1.I found that instead of 1/3 of the frame is shown, I got 3 whole frames shrinked into one window.
//So I made the height twice simply by painting 2 identical lines in the place of original lines
//2.I found sometimes there is an horizontal offset, so I added x_correction to move the frame back to center manually
//3.I changed video_buffer's type, from ui::Color to uint_8, since I don't need 3 digit to represent a grey scale value.
//I was hoping that by doing this, I can have a longer buffer like 39936, then the frame will looks better vertically
