Disable the fetching of methods when gem is loaded about flickraw

[hanklords]

Flickraw is not usable if it does not fetch the methods. If you do not use it in your test environment, do not require it. (You may have a particulare use case)

I believe the logic for this should be outside the library:

if environment != 'TEST'
  require 'flickraw'
end

If it doesn't fetch the methods in require 'flickraw', then the library is in an unifinished state, ie you can't use ruby introspection methods or flickraw's flickr_methods, flickr_objects, etc...
Additionally if the methods are fetched on first call, this first call has a different behavior than the following call, like longer delay and the modification of internal objects.

That said, I pushed some code and it is now easier to switch to this behavior, you can see f4b281d4479bbb49b3e1f1d16fd802aebd7ecf85.

You can fork the branch noload and activate github gem building option if you want a gem.

I have added options support to flickraw. Now you can do that:

FlickrawOptions = {:lazyload => true}
require 'flickraw'
