Support RC proxy XMPP presence (#29)

* Prompts user to elevate if LCU is running as admin
Doesn't crash to access denied exception
Bumped version to v1.4.1

* fixed path when registry entry is not found, added new registry location

* fix if RiotClientInstalls.json exists, but no Riot Client or corrupted

* use List instead of Array for RC paths

* Target .NET 4.8; support .NET 4.6+

(.NET 4.6 is included since first Win10 release)

* use WebSocket to monitor chat status changes

more reliable reflection of masked status in client
does not break after leaving/joining lobbies or exiting games
changed IsValidLCUPath to check for system.yaml instead of Logs folder

* add reference to netstandard, just in case...

* use TLS 1.2 to handle random WebExceptions

* fix _ws assignment and check for null, remove redundant code

* Update LCU status only on gameflow phase change

* fix status on startup, as gameflow isn't changing now

* fix not being able to change status when disabled

* support RC proxy XMPP presence
