Add REPL as package dependency

[fingolfin]

That should fix the Travis build failures with Julia nightlies

The commit looks good, but Travis seems to have failed again?

[fingolfin]

Yes, more changes are needed. And in fact, I am not so sure the change in this PR is needed / necessary either. It does not really help, in any case. My next best guess comes from JuliaLang/PackageCompiler.jl#194 where a similar error appears, and there, it was worked around by setting JULIA_LOAD_PATH. So I wonder if perhaps in Julia nightlies, when loading Julia from within GAP, it somehow fails to "find itself", i.e., the julia directory with the stdlib/REPL/ subdir in it...

[fingolfin]

It seems that for the nightly builds, a completely wrong version of GAP.jl is being tested, so any change I make here has no effect there. I am fiddling around in the hopes of finding a way to resolve that.

Looks good, thank you :)
