[Libreoffice] HTML_ColorEntry sal_uLong->sal_uInt32

[Chr. Rossmanith]

Hi,

I think the variable nColor from struct HTML_ColorEntry in htmlkywd.cxx 
can be changed from sal_uLong to sal_uInt32. Continue to change return 
type of GetHTMLColor as well and remove #include <tools/solar.h> 
afterwards (was playing with include-what-you-use which tells me which 
#include is used for which purpose).

Any veto?
