#1160 Customising changebar colours

[Vicent]

SUMMARY: At version 20.03, the colours for the changebar are fixed. It would be nice making them configurable.

---

Currently, the colours that are used in the changebar to identify those lines with unsaved changes or recently saved changes are fixed to yellow and green, respectively.

This is actually "hard coded" in sdk\cbeditor.cpp:1619, according to BlueHazzard at this forum thread.

It would be nice to have the possibility of changing this in Settings --> Editor... --> Margins and Caret, for instance.
