- Simplified the API
	- `require('requirefresh').requireFresh('the-module')` is now `require('requirefresh')('the-module')`
	- `require('requirefresh').requireFreshSafe('the-module', next)` is now `require('requirefresh').safe('the-module', next)`
- Removed domains from safe method, seemed out of scope to have them there (there is now just a try..catch)
