merge fix utf8

accommodate mem limit in php and java, using new box64

add option -A <opt> to box. This options allow more argument to be explicitly passed to the program We have to use this because if the argument we wish to pass to the program is option (in -? format), box will intepret it as its option and failed accordingly. be noted that, by the definition of getopt, these options will be put after original argument (check the code for more info)

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)
