Special request; Lasso Select (thanks andy for nagging! :)
Is committed now for further test;

What works:
- Hold CTRL while leftmouse-draw (gesture) for lasso-select
- Hold also SHIFT for lasso-deselect
- In Object mode it only selects on object centers now
- In Mesh edit mode it works on same level as borderselect

Not:
- other editmodes or objects in general

Also fixed crash with circle-selecting outside of window edge.
Also put back wire-extra draw for curves (previous trial broke mball wire)
Turned borderselect, circle, lasso into dashed lines for visual language.
