Module post osx screen capture

This module takes screenshots of the user's desktop, temporarily saves it to the temp folder and downloads it to the metasploit loot folder.

Module parameters allow for delay and number of screenshots to be configured. The COUNT parameter can be set to 0 in order to take screenshots until the attacker aborts the execution.

A local filename can be given, which will always point to the latest screenshot. Image preview programs will detect a change in the file and reload the image which gives real time surveillance (ish).
