Use a table format for list of plugins

[ericwb]

Rather than showing the plugins as a simple list, this change puts them into a table. It also clearly separates active vs. removed plugins for clarity.

Also discovered as part of this change was that snmp_weak_cryptography plugin doc file was incorrectly named with the duplicate ID of 508 instead of 509 as it should be.
