Fixed segfault in event/new_sched 

Fixed a segfault in the new event scheduler

Cleaned up some code that dealt with converting
xmlrpc_c::value_strings to C string constants to avoid further memory
corruption issues.

Also converted AddAgent(), AddGroup(), AddUserEnv() to take 'const
char *' pointers instead of 'char *'s to silence GCC's warnings about
invalid conversions from 'const char *' to 'char *'.
