Help and ReloadConfig command

Added two new commands!
Added '/pm help ' to show some useful infos about the PluginManager commands.
Added '/pm reloadconfig ' to reload the config of other plugins even if they don't have a dedicated command for this.

Java 12 support

Thanks to @LaserSlimeHD for pointing out that PM was not usable with Java 12

Finally a new release

This release finally contains the pretty much recoded PluginUtils by @MAXOUXAX and adds official support for 1.16.X

Removed Debug code

I accidentally left some debug code which would make the gui unusable

Fixed bug with GUI and update command

I fixed a bug within the gui code which caused an exception when having more than 54 Plugins.

Also new is that all plugins you now download from spigotmc using the download command are added into an own config which keeps track of the versions of the plugin. I added the update command to automatically update those plugins ingame.

Added many new things!

Added:

• Permission for /pm download direct and /pm download spigot (Can be turned off in the config)
• Support to hide all PluginManager commands a user does not have permission for
• /pm permissions now shows child permissions
• /pm dump now also shows child permissions
• The list with all PluginManager commands is now sorted

Added dump command

Using the dump command you can dump all plugin informations into a file for better overview.
Also fixed some bugs in the code.

Now compatible with 1.14.4

Added 1.14.4 support.

You can now load plugins by file name!

You can now download plugins by filename and finally have a permission for the download command.
Also fixed some things...

Added MVdWUpdater support

Added support for the MVdWUpdater Plugin as a soft dependency and made /pm update command multithreaded.
Fixed bug when tab completing a sub command which does not exist.
