Small profiling helper

[David Faure]

The attached header helps doing manual profiling using QTime.

The usual way of using a QTime and elapsed() works at the high level
(around one call) but not in a nested method called many times
from a higher-level loop.

It's quite simple and stupid but it works nicely - using the results
I could improve search-n-replace in KWord (in  the "without prompt" case) 
by a factor 32 ;)

Should this go in e.g. kdesdk, or is it really too simple and stupid
compared to real tools, e.g. gprof etc.? ;)
