Fix hardcoded file paths

[NetworkJack2]

There are a few issues with them

1. They aren't easy to find in the script
2. There is no config file or --option to set them at run time
3. The defaults are not sane on a few counts. directories in root in UNIX/UNIX-like is a no no. Capitalization is also a no no.

Affected:

appdir="/SYWorks/WIDS/"
macoui="/SYWorks/WIDS/mac-oui.db"
LogFile=appdir + "log.txt"

Recommendations

1. Expected SANE defaults:

appdir="/usr/share/wids/"
macoui="/usr/share/wids/mac-oui.db"
LogFile= "/var/log/wids.log"

2. Put these variables at the top of the script before exporting them as globals. Make them easier to find.

3. add --options for setting these at run time, and parse a config perhaps /etc/wids.conf or something.

Further, its recommended you use argparse for parsing --options.
