Handle also int colors in colon separated string

Browse Source 
Bug: 0x112233:0x445566 in YAML input didn't convert such colors
to #112233:#445566 and the strings where just passed as uppercase
to the .gv file. Hence Graphviz printed warnings about unknown
colors and used black as color instead.

Add test for int as string. Re-ordered if statements to give an
exception when a color has an unknown type.
