Autopwn

* Added option to specify assessments directory
* Added parallel command line option (overrides
all other parallel options specified)

* Added timezone info to logs
* Modified parallel option in tool configs to booleans

* Greater than and less than rules now work

* Fixed bad bug where redirection locations were being used as
targets (had to shell=True the Popen(), will fix properly
sometime)
* Added stdout option to tool configs. If a stdout log should
be generated for a tool, then "stdout: True" should be specified,
if the tool output is being redirected to a file already,
"stdout: False" should be used so an empty stdout isn't created

* autopwn global configuration file added
- parallel option (overrides assessment config option)
- scripts_directory (directory containing tools)
(currently does nothing)
* screen support
* Split tool stdout and stderr into logs
- Tools no longer require redirection nonsense

* Changed target file format (had to happen)
* Included URL path option
* Bug fixes
