Reduce konsole startup time
lately konsole has become so slower to start on my machine. Yesterday out of annoyance, I decided to find out why. strace showed fdatasync call was taking the most time. First call to fdatasync was coming from here
After this patch, konsole is working just fine. It can remember the last set colorscheme. The start time improved from around 1200ms to just 200ms
I haven't tested other apps to see if this breaks them or not.
Also IMO, there is no need to have functionality to change colorscheme of window in konsole.
