Fix #68 honor ITEM_URL setting with no trickery

[ralphsmith80]

Uses the dictionary get method providing the app.config value as the default so that settings.py values are not clobbered.

[ralphsmith80]

My guess is the tests are failing because the eve-sqlalchemy was setting the item_url to 'regex("[0-9]+")' and now that the eve default is being used it's getting set to 'regex("[a-f0-9]{24}")'.

If that is the case the fix should be to add ITEM_URL = 'regex("[0-9]+")' to test_settings_sql.py.

[ralphsmith80]

Not sure what's up with the tests now. Running the the py27 tests work on my system. The only difference I've noted is that the travis job is using python 2.7.9 and my system is using python 2.7.10.

Here's what my system output looks like.

Just used pyenv and pyenv-virtualenv to test with python 2.7.9 and test still pass on my machine.
