Issue #184: Added an integration test for RtGist.fork()
#192 
src/main/java/com/jcabi/github/mock/MkForks.java:44-46 has to be
resolved: Need to implement the methods of MkForks: 1) iterate,
returning a list of forks, and 2) create, which will create a new fork.
Don't forget to update the unit test class {@link MkForksTest}.
