ElementAPI compatible with item getters

Please, provide access to HTML attributes through item getters.

The following code makes three assertions of which only one works.

import operator
import splinter

b = splinter.Browser()
b.visit('https://www.google.com/')
q = b.find_by_name('q').first

assert 'q' == q.get('name')
assert 'q' == operator.itemgetter('name')(q)
assert 'q' == q['name']

I would write the change myself but I have been unable to properly run the test-suite.

@rg666 Go for it.

@rg666 I don’t see any bugs involving item getters or missing functionality. I encourage you to write unit tests for the behaviour so we can verify they work. If the unit tests pass, I’ll close this issue.
