Support 50Hz(PAL) (#648) (PR #658) 
- Added Configuration GUI to include checkbox for "50Hz"
- Implicitly use PAL or NTSC base 6502 clocks depending on video refresh rate
- Added new -50hz and -60hz command line switches
- Updated save-state for video refresh rate

// SoftCard SW & HW details: http://apple2info.net/images/f/f0/SC-SWHW.pdf
// . SoftCard uses the Apple II's DMA circuit to pause the 6502 (no CLK to 6502)
// . But: "In Apple II DMA, the 6502 CPU will die after approximately 15 clocks because it depends on the clock to refresh its internal registers."
// ref: Apple Tech Note: https://archive.org/stream/IIe_2523004_RDY_Line/IIe_2523004_RDY_Line_djvu.txt
// NB. Not for 65C02 which is a static processor.
// . SoftCard controls the 6502's RDY line to periodically allow only 1 memory fetch by 6502 (ie. the opcode fetch)
//
// So save ActiveCPU to SS_CARD_Z80 (so RDY is like IRQ & NMI signals, ie. saved struct of the producer's card)
//
// NB. Save-state only occurs when message pump runs:
// . ie. at end of 1ms emulation burst
// Either 6502 or Z80 could be active.
//
