plugin.yml Update

Silly copy/paste error from the SimpleList plugin.yml.
Caused plugin's command to not be recognized.
BugFix / Redundancy Update

Removed PluginDescriptionFile use, as Bukkit already outputs plugin
status and version onEnable().

ReloadPlugin() now calls to onReload(), instead of onEnable().
Doing this allows me to push that the plugin has been enabled, without
redundancy in the original onEnable().
Afterwards, onReload() calls onEnable().

Proper return state called after successful command use. Fixes bug where
every command returns btNoPermission string, despite command working.
