Wrong number of arguments on call to artSkinSelectInfluence

I was getting an error with this line.
https://github.com/bungnoid/glTools/blob/8ff0899de43784a18bd4543285655e68e28fb5e5/tools/smoothWeights.py#L243

```python
# Line 1.57: Wrong number of arguments on call to artSkinSelectInfluence. //
```


I changed it to this and it works now:
```python
mm.eval('artSkinSelectInfluence artAttrSkinPaintCtx "'+influence+'"')
```
