Add support for 2.1.2

[jiripospisil]

I'm not really familiar with the code base but it seems this is all it takes to get it working with 2.1.2p95.

Fixes #125

any updates on this failing test ? is it ready ?

[flipkick]

the test doesn't fail because of this commit, but because of using ruby 2 now instead of ruby 1.9 for running the rake tasks.

before in https://travis-ci.org/cldwalker/debugger/jobs/19734278 :

 rvm use 1.9.3 --install --binary --fuzzy

now in https://travis-ci.org/cldwalker/debugger/jobs/19734279 :

 rvm use 2.0.0 --install --binary --fuzzy

using ruby 2.0.0 here in the travis setup would also break the tests for a version without this commit. using ruby 1.9.3 the tests would pass with this commit.

Known Issues

• Only 1.9.2 and 1.9.3 are supported. For 2.X rubies, consider using byebug or debugger2.

Closing since I'm scoping debugger to just 1.9.2 and 1.9.3. For more see #125 (comment)
