Disable dynamic plugin reloading

[FWDekker]

Instead of fixing #520, this just disables the dynamic reloading feature.

I spent more than 6 hours trying to find out why dynamic reloading didn't work, found a bunch of supposed memory leaks, and then found extremely insufficient documentation on JetBrains' end on alternative design patterns to avoid those leaks. (Apparently every single Companion object was still referenced by the classloader. How am I supposed to avoid that?)

It's not worth my time. By explicitly disabling dynamic reloading, at least users won't see their IDE trying and failing to dynamically reload the plugin.
