One Light Kat (Atom syntax theme)

Improved (IMO) version of One Light. Works best with Apple's SF Mono font.

Changes from the original:

• Background is #ffffff.
• Text is fully monochrome (saturation 0%).
• Function calls are blue in Python (with MagicPython).
• Operators are cyan.
• Comments and line numbers use light font weight (300).
• Keywords, types, and language-specific constants are semibold (weight 600).
• Function parameter names are italic (in many languages).
