Fixed some enable issues on Bukkit version. More:

Tested functioning:
- Enable
- Reload
- Analysis & Inspect command
- Debug page
- WebServer functions partially

Tested not functioning:
- /player/playername (Null response)
  - Some PageHandlers return null Response (Not supposed to)
- /server/  (Endless "Refreshing" page)
- /server/name
  - Style responses not found in sub folders (eg /server/page)
- /players (jquery.dataTables.js Unexpected token)
- Internal InfoRequests do not work as intended
- Internal errors in RequestHandler
- /plan manage backup, restore, setup

Not Tested, probably not functioning:
- Bungee
- /plan manage setup

Not implemented:
- Player online information to transfer table
- Config setting transfer
- Bukkit - Bungee Set-up
