integrate with travis. remove all the gtk stuff.

make travis use latest vsns of erlang 15, 16, 17, and 18.
move sherk et al to its own repo.

+eper is a loose collection of Erlang Performance related tools.

+* dtop   - similar to unix top
+* ntop   - visualizes network traffic
+* atop   - shows various aspects of the VM allocators
+* redbug - similar to the OTP dbg application, but safer, better etc.
