A few fixes.

Those fixes:
  - Remove NSA completely. Metrics is not needed. This is a custom build.
  - Rewrote Hotfixer loading system. This is grouped with the "Fix HotFixer  not identified a real plugin" commit. This fixes the "must have 1 plugin" bug.
  - Remove startup delay. Some people are complaining they get slower startups.
  - Remove the updater. It isn't used in the code anyhow and this is a custom build.
  - Fix /version showing unknown API version. Please update on each build.
