LocalDebuggerEnvironment string

The local debugger string setting in the *.vcxproj.user file looks a bit wrong when first setup by the plugin (although it still works):

<LocalDebuggerEnvironment>
PATH=$(QTDIR)\bin%3b"$(QTDIR)\bin%3b$(PATH)
</LocalDebuggerEnvironment>

I changed it to:

<LocalDebuggerEnvironment>
PATH=$(QTDIR)\bin%3b$(PATH)
</LocalDebuggerEnvironment>

which looks more correct and it still seems to work OK.
