Fixed bug 2673
Speculative fix for bug 2667.
Merge branch 'master' of github.com:sk89q/commandhelper.git
Optimized some code in EntityManagement.
Added http_request().

Finished the PublicSuffix security checking in the web utils, and broke them all into their own package. The WebUtility class is now complete, though it may need a bit of tweaking and bug fixing, but the primary use cases are working. The http_request function is also added now, and also appears to work.
Added xml_read, though this may not be its permanent home or signature.
Updated docs and made it so interpreter mode works with async things.
Allow no scoreboard arg on set_pscoreboard, added get_functions, get_events, get_aliases, material_info, and reset_all_pscores
Add javadocs for new methods, and make player_move match the documentation
Merge pull request #120 from jb-aero/test
