add a new modified sandbox "box" The original file was pulled from moe (git://git.ucw.cz/moe.git) by Martin Mares's commit on Sun Jul 29 23:53:56 2012 +0200 The modification is to make it separately compilable and add more option to specify additional argument to the program. (Please see usage guide) run `gcc -o box -std=c99 box64-new.c` to compile.

add options for grading all submissions of a specific problem (grafted from branch algo-bm 8ed1c0aa59eaf8e22e40fc765c1fba4ac88a34b5)

add auto setting of config.time_zone to be the system timezone (from either /etc/timezone or /etc/sysconfig/clock)

It seems like WEBrick needs this.

handle the case when problem id or submission id is null. Grader will simply skip such request. Add more report on console (for command line grading) (mercurial grafted from d233105d3965c5368c9b33125f390e39b25f910e)

fix logg() in compile, add more logging to engine.rb when the problem cannot be found

change hashbang to /usr/bin/env ruby

preserves script permission in import_problem script
