    Make AddressRange inclusive (fix ADDR_ANY)

Commands window:
    Support more commands in code editor
    Add "Step over" button
    Improve GPR read/write highlighting
    Fix crash from viewing unmapped memory

Memory viewer:
    Add memory locks feature (interpreter mode only)
    Make auto-refresh optional
    Fix crash from viewing unmapped memory (can now view memory-mapped registers)

Stack viewer:
    Fix crash from viewing unmapped memory

I also went ahead and fixed PJ64's settings window for Wine, so Linux users shouldn't need to manually edit the config file anymore.

The development build section on PJ64's website was made public (https://www.pj64-emu.com/nightly-builds), so I'm no longer uploading github releases to my personal fork.
