[Qgis-developer] freehand plugin errors

This behavior is related with layer properties, not project properties. 
I was little searching in API and found only one promising function: 
geographicFlag() in QgsCoordinateReferenceSystem class, and is really 
far beyond my imagination, how to connect this with QgsMapLayer. At 
least i added "Use preferentially with layers projected in rectangular 
CRSs" to plugin description.

Single click issue is (hopefully) fixed in newly uploaded version 
(0.2.1) of plugin.

I was little bit testing my plugin and would like to please dev of 
avoidIntersections function of QgsGeometry class, if he could have a 
look at behavior of this function in combination with my plugin. I am 
attaching two pictures describing this situation: you have two polygons 
created with Freehand editing plugin with avoid intersection function on 
- everything went OK, but when you want to add another one (with avoid 
intersection function on), newly added polygon is in 50% of cases corrupted.

Thanks to Giovanni for testing

Regards
Pavol
