new area fill toolbar dropdown

The GSOC 2014 Color Selector is in LibreOffice 4.4, but it's not used for the "area fill" dropdown in impress or draw. So I spent a little time today for LibreOffice 5.0 to hack things up so that instead of using the old color drop down list for that we now have the new color selector in the toolbar instead. Gives access to custom colors, multiple palettes, and recently used colors all in one place.

And here's the old one for reference, I've backported the above change to Fedora 22's 4.4.X to address some in-house vented frustration at selecting colors in impress.
