Add Inline Color Picker Plugin

Merged Jan Paul Batrina requested to merge jbatrina/kate:colorpicker-plugin into master

Inspired by https://kate-editor.org/2018/08/17/kate-gains-support-for-inline-notes/.

The supported colors are from QColor. See https://doc.qt.io/qt-5/qcolor.html#setNamedColor.

I'm new to plugin development, so I based mainly on the konsole plugin. Improvements and Suggestions are very much welcome! colorpicker_testvalues colorpicker_dialog colorpicker_config
