#111 fix konsole notification color and send Jekyll a patch!

[Ritesh Raj Sarraf]

Konsole, along with the plasma theme, has a very handy feature. Say you run the command `find . | grep foo` in one of the tabs in konsole and switch to the other tab. To know when the task completed, you need to switch to the tab to verify. Konsole (with plasma) changes the color of the font of the tab where the task is running, upon task completion. This is a very small but handy feature which helps to know that there has been some activity in the other tab.

This feature does not work when using Bespin.

Yesno - actually it does work. Despite konsole.
There's however a contrast check because the way konsole does this _can_ cause invisible text (it basically assumes the tab is window colored and sets the painter, expecting the style is not gonna alter it)

a) the default purple does not contrast with black, so it's ignored
b) you can check yourself by
1. using a different config (with the window or some other bright color for the tab background)
2. alter tabbing.cpp (lookout for "customColor" and comment the "if (Colors::haveContrast...)" line alongside it, should be 2 occasions
c) since meanwhile konsole is maintained and maintained by a friendly guy, i could actually "fix" it and send him a patch ;-)
