repl: Support cross-session history

[xTVaser]

Linenoise had all the tools already to support this, the problem (and i could very well have solved it in a less than ideal way) is that the history is stored in a static vector. Being as we have to interact with the history in different points of the app (ie, load the history on startup / save it on exit / etc) these are all in different files, and when doing so the history would be empty.

Wrapping everything to have a single linenoise include, "solves" this problem, and history now works as expected.

It will save a .opengoal.repl.history file in your (linux) $HOME or (windows) $USERPROFILE directory.

This is awesome, it makes such a difference to have the history saved.

The static history is really annoying, but I think your wrapper is a good solution.
