Request.is_method should be changed to eq_method?

[Jaymon]

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")
