Linux Implant - cron.py

[montysecurity]

Hey!

I wanted to get this to you as soon as possible. Here is where it is at right now.

• As noted in the commit message, this has not been tested (passed python cron.py to check for syntax errors).
• Between the ideal scenario of supplying English text to cron and the more programmatic approach of parsing a cron schedule, I opted to a medium where there are predetermined schedules to choose from for now. The goal it to get this to as English as possible (e.g. daily at 1730) but for right now there are 5 preset cron schedules to choose from that are supplied as English text.

I wanted to at least get this posted to give you a chance to look it over and provide feedback while I go through the documentation and make sure I am utilizing the pwncat API correctly
