Combining branches

[jacobtread]

Description

Merging all the current development changes from dev over to the master branch, switching from a feature -> dev -> master branch layout instead to a feature -> master layout. The master branch will now contain the latest changes rather than a separate dev branch.

Compiling the latest version from sources now should instead use a specific release tag rather than the latest branch unless you are okay with possible breaking unreleased changes.

Changes

• Better handling for internal game admin logic
• Changed how subscriptions are handled
• Lots of docs updates and notes from new findings
• Nginx client auth example code
• Config variable for specifying a specific host to bind on
• Various README changes and notes
• New locking queue for ensuring packets appear in the correct order without weird delaying behavior
• Reduced QoS probing requirements
• Manually rewrote handling for session read/writing to improve reliability, performance and memory usage of the previously sharded and disconnected read write handle system
• Removed unnecessary task spawning
• Replaced short lived async locks with parking_lot lock primitives, these locks are immediately unlocked after swapping or copying a value so there is no need for async acquisition and all the colored functions that creates
• Replaced read/write locks with mutexes in places where read/write lock is not as useful
• Added additional QoS options (Disabled, Hamachi)
• Handling for UPnP packets
• Generated game protocol version hash at runtime (Not too special but could be useful later on)
• Removed lots of unused or outdated code
• Partial frame persisting to improve packet decoding in cases where the entire packet is not immediately readable
• Replaced existing generated leaderboard system (Which expires and is updated at fixed intervals) with a persistent leaderboard that is stored in the server database
• Dependency updates
• Development seeding code for seeding the database with many users

Breaking changes have bumped the version to v0.6.0-beta
