Request.is_method should be changed to eq_method?

I'm starting to standardize on:

* `eq_*(value)` - takes one value and compares it against something internal
* `is_*()` - True if some internal condition is True
* `in_*(*values) - True if some internal value matches any of the passed in values
* `has_*()` - True if some internal value exists

So if I'm using that standard then `is_get()` works but should call `eq_method("GET")`
