Keiko | Server security and plugins inspections

Keiko | Server security and plugins inspections -----

Server plugins inspector, runtime connectivity and file access control, activity monitor, and more.

3.0.0

New static inspection. Keiko will now detect some types of pirated ("leaked") plugins and report them. Because "cracked" software copies are often infected.
Standalone mode.
- You can now run static inspections without starting your server using the new inspect [jar] command of keiko-tools. This also allows you to scan just one specific file and not the whole plugins folder.
- Starting keiko-tools will now be treated almost like an ordinary Keiko startup. One of the consequences of this is that starting keiko-tools will now automatically delete old Keiko logs (configurable). Another one, also related to logging, is that the output of keiko-tools will now be saved in log files as well.
- The output format of commands in keiko-tools now matches that of Keiko itself. In other words, it's now more readable and informative.
Minor code optimizations.
