Improved support for escape sequences

[Roslund]

This should resolve #5. I have changed the stripping pattern to account for additional escape sequence. However, I am not aware of all escape sequences, so I might have missed something.

All test passes and I have tested it with the example provided by @kiliankoe in the issue thread.
I have also added two additional stripping test that fail on master.

I would advise some testing before merging.

@jpsim could you please take a look at this one? I'm personally using it on some CLI tools and works pretty well with Rainbow.
