Submenu text colour

[dt192]

Describe the proposed feature

Add option to set submenu text colour

Explain how the feature may be useful

You can currently set the submenu background colour, but not the text colour resulting in for example text colour being light against a light background.

Adding this seems to work

OPTION_COLOR CUSTOM_SUB_TEXT_COLOR=Customize submenu text color,0,TRUE,000000

[CUSTOM_SUB_TEXT_COLOR]
Submenu_text_color=#FFFFFF,#FFFFFF,#FFFFFF,#FFFFFF
Submenu_text_color=#000000,#000000,#000000,#000000
Submenu_text_color_mask=#FF0000,#FF0000,#FF0000,#FF0000
