Plugin auto-copy overhaul

[Sniperhid]

When merged this pull request will:

• Removes the config file and instead directly compares the dlls
• Adds Roaming application data folder to scan list - In a manner compatible with the TS 3.1 usage of the registry (Partially addressing Teamspeak 3.1 Support #83)
• Skips searching non-existent folders - Should registry/users not be updated. It will however create the plugins folder if it does not exist.
• Prefer AppData over Program Files due to its lack of requiring admin privileges. As teamspeak prefers program files over AppData in plugin load order precedence. This will remove the plugin from Program Files if copying to AppData

I know it's WIP, but snake formatting as per coding style guidelines.

Opening brace on same line as per coding style guidelines.

@jonpas - addressed seeking updated review. Tested this locally myself and seems to work well

Looks good code wise, however it's still not using snake formatting (I clicked approve before checking that). I think we should also get rid of the old code.

Awesome work @Sniperhid !
