Send document colors with lok callback

First step for publishing any palette for LOK.
Let's start with Document colors (colors used in the
document) which can be extracted similar to theme
colors from SfxViewShell.

Modify generateJSON function so it appends palette into
existing ptree/JSON.

In the next step we can make it more generic so it will
be able to send any palette managed by PaletteManager.
