Dancer's load DSL keyword causes prototype conflict with Module::Load

Hi,

The load keyword is now exported by default by Dancer, so it causes a prototype mismatch when I use this Test::WWW::Machanize.

Here is an example warning:

```
Prototype mismatch: sub Test::WWW::Mechanize::Dancer::load: none vs (*;@) at /Library/Perl/5.16/Module/Load.pm line 29.
```

This change fixes the problem by no longer allowing load from Dancer to be exported.

Thanks,

Rusty
