Back and forground index export

[LokiMidgard]

This is an proposal to store background and foreground color index.

I've added two section screen and popup. Both sections contain two keys FORGROUND and BACKGROUND. The assignable values are keys of the table section.

sample

[table]
DARK_BLACK = 12,12,12
DARK_BLUE = 0,55,218
DARK_GREEN = 19,161,14
DARK_CYAN = 58,150,221
DARK_RED = 197,15,31
DARK_MAGENTA = 1,36,86
DARK_YELLOW = 238,237,240
DARK_WHITE = 204,204,204
BRIGHT_BLACK = 118,118,118
BRIGHT_BLUE = 59,120,255
BRIGHT_GREEN = 22,198,12
BRIGHT_CYAN = 97,214,214
BRIGHT_RED = 231,72,86
BRIGHT_MAGENTA = 180,0,158
BRIGHT_YELLOW = 249,241,165
BRIGHT_WHITE = 242,242,242

[screen]
FOREGROUND = DARK_YELLOW
BACKGROUND = DARK_MAGENTA

[popup]
FOREGROUND = DARK_CYAN
BACKGROUND = BRIGHT_WHITE

I'm okay with this for the time being.

Ideally, I'd want to also have a way to export the "terminal" default foreground and background colors, but since those aren't really query-able, nor set-able with VT, then it doesn't really make sense to include them in the scheme currently. We can come back and add support to colortool for those later, once the support is there in the console itself.

I think I got all "forground". I also added the popup attributes to the JsonParser
