Proxy Support for Sonarr #732

Switch to use Port #0 which just uses the next free port
Non Functional - Code Cleanup
Tabs -> Spaces,
Opps Deleted too much
Refactoring & Code Cleanup & Move Config to DB
remove unneeded line
Clean Up Spaces
Code Review Points on the UI
FIx extra space
Clean Up unrequired changes
Add a HealthCheck.
Extra Check in ProxyCheck. Correctly deal with Socks Authentication
Remove SubModule
Add in Nuget + Tweak ProxyCheck
Code Review Points
Missed Review Point
Add Subnet Filtering, Add ProxyBypass for local addresses. UI updated for property changes.
Fix typo, and copy&paste error
Tweak URL to hit
