Sitemap editor: Trim spaces from color value (#2091)

When generating the sitemap DSL from a UI configured sitemap with color
conditions, if the color in the condition has a leading space, it will
be included in the color string.
While this does not have an impact on the sitemap functionality (it
works), it is an issue if one would copy this sitemap to a sitemap file.
This PR strips the blanks from the color.

See #2082 and the example provided there.
