[Konsole-devel] Support for dim color support, i.e., \e[2m [includes patch]

I have refreshed and refactored this patchset. All default colorschemes have also been patched to support faint intensity---as well as the new
Breeze theme.

Is there any interest at all in supporting additional SGR codes?
