Describe the Enhancement

During development of a METplus wrapper for the Plot-Point-Obs tool, @georgemccabe noted two issues:

1. The Plot-Point-Obs config file currently lacks the tmp_dir configuration option. This is an oversight, and it should be added.
2. He also found that passing an empty configuration file to the MET tools results in a runtime error. This can be demonstrated using the test_config utility:

touch empty_file ; internal/test_util/basic/vx_config/test_config empty_file
...
ERROR  : yyerror() -> syntax error in file "/tmp/met_config_3387_0"

This task is to fix both issues. While 1. is a mandatory, the fix for 2. is only desired.
