More abstraction, a few test commands, and a ton of other changes

Full changelog:
 * Most JavaDocs have been added; all the least-straightforward code has been documented
 * Command is now renamed to Module
 * Further abstraction of Module, new UX features, more elegant and redundant class code
   - New ModuleInfo container class for command module metadata, with a Builder included
   - Added command descriptions
   - Separated required permissions into bot permissions and user permissions
 * package-info.java for all packages and package-level categorization via @CommandPackage(CommandType)
 * CommandType is now automatically populated in ModuleInfo
 * Added 'help', 'purge', and 'claimoperator' modules
 * Operator commands no longer rely on a hardcoded ID to check operator status; use 'claimoperator' to set and change bot operator
 * User permissions are now properly calculated & checked
 * CommandType now provides Emoji icons for each type
 * Migrated property configuration from Spring to Owner
 * Added '--debug' command-line option to make lower-level logging accessible
 * CommandDispatcher now uses an ExecutorService to start command threads instead of manually creating threads
 * Module scanning & instantiation moved to separate CommandRegistry class
 * CommandContext now provides the bot's Member as well as the invoker's
 * Upgrade to Java 10 and modularize the application
   - Note: 11 is definitely preferable, since it's the current LTS, but Hibernate depends on the java.activation module
     which was removed in 11. Once I can find a way to get jlink to recognize either the module from the Java 10 JDK or
     the non-modular Maven artifact, ghost2 will be migrated to 11 immediately.
