Loading changes

- Server plugins are no longer case sensitive with file names. For
plugins that have a client side part, you still need an all lower case
folder name. It's best to stick to lower case names really.
- Fixed reserved slots plugin logging that it's opening the server on
every disconnect below the password threshold.
- Changed where Shine injects itself into the game code. This should
mean it no longer gets blocked from loading by any mod, unless they
randomly decide to copy and paste the ConfigFileUtility.lua file into
their mod?
