LizardmanShamanPlugin: Rewrite

[rdutta]

Addresses #2174

• Removes Notifier feature as the in-game message no longer exists (I believe)
• Removes the pie overlay timer (which is pretty useless)
• Draws an overlay for Spawn walkable/explosion tiles (more useful)

You should put yourself in the licensing header instead of openosrs if it’s your code

If parts are from the removed files just add yourself in addition to openosrs

I always thought this plugin needed a rewrite.
Nice job

There is a checkstyle file you can import to intellij that will fix most of these code style issues, I highly recommend doing that, then using the reformat code right click option in intellij.

Imported the checkstyle and made the suggested changes.

Added name to licensing header.
