version 0.7.1, upgraded dependency on method_source to 0.4.0 so that

accurately returns C source for immediate value instance methods.

* refactored repl into 2 help methods: repl_prologue, repl_epilogue
* added session_target method to Pry instances so can retrieve target
of session for parents, e.g _pry_.parent.session_target
* refactored ls command to use Symbol#to_proc
