ReflectFrom left []rune keys empty (unsupported type '[]int32'). MapTo had the same gap.

Treat []int32 (including []rune) as a Unicode string so a field like []rune("abc") writes prop.1 = abc and maps back.

Fixes #335

Thanks. rune is an alias of int32, so this treats every []int32 as text, e.g., ports = 80, 443 maps to character codes, and ReflectFrom writes []int32{80, 443} as Pƻ. As noted on issue 335, []rune stays unsupported, so please use string.
