Use of uninitialised value roundwordlist.

```
zarthus@frost.zarth.us ~/regolf$ perl main.pl
Trying to connect to '#regolf'
Use of uninitialized value $Regolf::roundwordlist in -e at main.pl line 38.
```

This is within the core bot at master (df54549b296b3c68c5a071284f2d59d76062b6e4)

I presume this to be due to `$wordlist` not being properly exported.

Reference #30
