Implemented running length and have fixed Wolfram's issue #13: event callbacks 
were done twice since both area and length measurement init (create()) each 
subscribed to _all_ OL Measure controls. Now callbacks are only called once. I 
have integrated some stuff for "Leg" (Teilstrecke") display but the output 
looks a bit funny. This has to be looked into. All code is in SVN
and example on:

(we can now discuss issues as comments in this issue tracker)

Please comment // line 40 and 61 'out += "  (" + __('Leg')   ...' - the wrong 
delta running length isn't shown anymore.
My code works only for a 'STATIC' length measurements - therefore you have to 
comment line 245 in 'ToolbarBuilder.js' instead to: // immediate: true, 
If done, the static length measurement shows the correct difference - but only 
when you do a click. 
My approach was to have a running tool - that works only with a new 'onclick' 
handler to get the 'measureLastLength'.

I hope I understand well and made your proposed changes except the immediate: 
true which seems to work ok. Feel free to modify otherwise.

btw if you hold SHIFT+Mouse drawing is without clicks.
