[Halla12_software] new version of go_table script

[Zhiwen Zhao]

Hi, guys

I updated the go_table script as described here.
https://hallaweb.jlab.org/wiki/index.php/Solid_geo

The change:
1. remove default database as clas12, a database naem has to be explicit 
as the first argument.
2. the 2nd argument is the table name. so the same script can be used 
for any table.
