Theme color and tint/shade attribute for SvxColorItem

To support theme colors the SvxColorItem must be extended with
an optional attribute theme index to define the index to which
theme color current color belongs and an optional tint/shade
attribute define how much the color ha been additionally tinted
or shaded.

[ Miklos: left out the potentially breaking svx/sdi/svxitems.sdi
changes. ]

(cherry picked from commit ccdbf815e00dbe2ba21f7e86b6743df100b7401f,
from the feature/themesupport2 branch)
