vdigit: changing a tool should cancel current edits

[msieczka]

r33285

1. add a vertex on a boundary

2. don't confirm with the right key, but select the "Move vertex" tool

3. try to drag the vertex you added - failure:

Traceback (most recent call last):
  File "/usr/local/grass-6.4.svn/etc/wxpython/gui_modules/ma
pdisp.py", line 1025, in MouseActions

self.OnLeftUp(event)
  File "/usr/local/grass-6.4.svn/etc/wxpython/gui_modules/ma
pdisp.py", line 1400, in OnLeftUp

self.moveCoords = (self.moveCoords[0] + dx,
IndexError
:
list index out of range

Selecting a different tool without committing the edit first (like in the case above), should automatically cancel the uncommited edits edits.
