General re-organization of some Tools sections, adds several tools.

This commit makes a substantial change by moving two sections that were
previously in "Tools" into the "Online Resources" category instead.
Specifically, the "Penetration Testing Report Templates" and "Code
examples for Penetration Testing" sections, each of which contained
references to documents rather than immediately-usable software, were
moved out of the "Tools" category. This was done because there is now a
clear distinction between "places to go to get more information about a
topic" (a resource) and "software to download that is immediately usable
in a pentest" (a tool).

Additionally, this commit adds a new section of Tools for pentests
tentatively called "Collaboration Tools" and adds RedELK, a Red Team's
SIEM, to that section. RedELK is an example of a multiple teamserver
analysis framework intended for use during long-term engagements for
keeping tabs on Blue Team activities, so it is not exactly like any
other tool in this list.

Finally, another tool (Cloakify) was added to the data exfiltration
section.
