v1.6 - NetMessage & HelpText rollback

- HelpText is now single-lined due to display issues (check Beta branch
for HelpDesc; it will require the unstable tshock build that added
HelpDesc)
- NetMessage is now being used in place of entire inventory updates.
Should fix any lag if it was causing any at all / contributing for
overall thread overload
v2.0 - Update and Rewrite

 - Updated for TSApi v1.2.4.1 & TShock v1.16
 - Rewrote whole plugin. Feels way more organized now.
 - Changed few messages.
 - /key mode now changes the config to match, allowing the setting to persist between sessions.
 - Added KeyChangerConfig.json example to DLL.
