2017-04-01main: exit with error on failure to init arenaJoshua Judson Rosen
This handler got broken when exit_nicely stopped actually triggering an exit from the entire process and started just exiting the guile thread. And, actually, it never exited with an error-status before-- which it does now.

2017-03-28REPL: just use guile's normal REPLJoshua Judson Rosen
This gives _much_ more useful readline behavior, since (ice-9 readline) actually knows how to autocomplete based on the scheme environment, handle multi-line input, etc.; and properly displays return values and error-messages, and supports switching to different front-end programming languages like ecmascript. Note that we're keeping catch_handler so that we have a chance of diagnosing problems that could _conceivably_ occur when interacting with guile during bootstrap (e.g.: missing readline support, changed REPL API...).

2017-03-28Drop unnecessary spinlock (loading, ploading)Joshua Judson Rosen
After some of the restructuring that was involved in the inversion of the GTK+/guile threads, these variables are no longer needed. Though note that we do actually still busywait specifically on creation of the map.
2017-03-28Invert GTK+/guile thread relationshipJoshua Judson Rosen
Making the GTK+ thread the main thread, and subordinating the guile thread, lets the GUI continue to live after the robot has died-- which means that we'll be able to switch to just doing everything in the GUI without requiring a separate xterm to see the final stats after the robot dies.
