Little beauty fault is corrected.

Three commits, one after the other! 81 is my, 82 is my fiancee's, 83 is my younger sister's birthyear :) In this commit Alpar's wish came true: editorial buttons are now available directly on toolbar.

Very small bug is corrected: if node creator tool is active, the small red arrows won't move, if you click on them and if you drag the newly created node... 'was hard to notice it :-)
