The format factory can be based on the abstract factory class if it
wasn't static. This allows for higher abstraction and makes future
extensions possible. Also, not all parts of RSS-Bridge need to work
on the same instance of the factory.

'uid' represents the unique id for a feed item. This item is null by
default and can be set to any string value. The provided string value
is always hashed to sha1 to make it the same length in all cases.

Adds unit test for bridge implementations:
- Custom functions must be in protected or private scope
- getName() must return a valid string (non-empty)
- getURI() must return a valid URI
- Each bridge must define constants for NAME, URI, DESCRIPTION and
MAINTAINER. CACHE_TIMEOUT and PARAMETERS are optional.
The unit test is written for PHPUnit 6.x and will automatically be
tested by Travis-CI for PHP 7.0 (see .travis.yml).
Remarks:
Unit tests for bridge data were scrapped in #378 for complexity
reasons (tests would have to be maintained for each bridge). This
unit test, however, is written for testing all bridges without
taking specific implementation details into account.
