* Create serverDZ.cfg
Added default serverDZ.cfg file for install script if it needs to be downloaded.
* [DayZ] Bug Fixing & Cleanup
Egg:
- Fixed mission persistence and mission parameters (like loot tables, etc.) being broken due to missing vanilla mission files in certain scenarios (ie. Steam account does not own the DayZ game).
- Fixed bugs that prevented the server from starting due to a missing `hostname` variable in 'serverDZ.cfg'.
- Improved the installation script to better accommodate Steam users with Steam Guard enabled and check for missing required files.
- Changed the installation script to not overwrite 'beserver_x64.cfg` upon reinstallation if it already exists.
- Changed the default Steam Query Port to be correct.
README:
- Added shaynendradika as a contributor.
- Fixed/Improved "Server Ports" section.
- Elaborated on the differences that game ownership makes in the "Installation/System Requirements" section.
- Updated the "Running With Steam Guard Enabled" section.
- Fixed typo.
* Fixed Configuration Files parsing for Pelican
`env` is now `server.environment` in Pelican panel
