Title: read_pajek() shouldn't require network name

Attempt to read in a network with no name (pajek doesn't require one be included), the following bit of code in pajek.py fails:
```python
if l.lower().startswith("*network"):
label,name=l.split()
G.name=name
```
because there is no exception if the *network line lacks a name.
