Bugfix, minor: color the overview customview correctly
When using a custom color (from the SYS2 menu, layout), the overview
customview was the only one presented in the wrong color. While the fix
for this is rather simple (in hindsight), it was a non trivial search
trough rather obfuscated code.
There is a specific function to set the text color index on this page, but
this only worked for a single line text string, that has the color index
byte as the very first character. The original author already recognized
that this function "could be extended", but left this extension as an
exercise to the reader.
So, the coloring is fixed by extending the function, and actually using
it for the overview customview.
