Updates logic to handle setting the URL sent to the CH5 wrapper app to use the CS LAN IP based on the actual IpInformationChange event on the panel itself.
- Added `._PepperDash.Essentials.4Series.sln` to .gitignore.
- Introduced new using directives for Regex and Crestron libraries.
- Added `csIpAddress` and `csSubnetMask` fields to store device IP info.
- Modified constructor to retrieve and assign current IP and subnet mask.
- Updated `Panel.IpInformationChange` event handler for logging and URL setting.
- Created `GetUrlWithCorrectIp` method to determine the correct URL based on IP.
- Refactored `SetAppUrl` to utilize the new URL method.
- Commented out old IP determination logic in `MobileControlWebsocketServer.cs` as it was moved to the touchpanel controller.
In order to solve some dependency issues that keep cropping up, MC
should be moved back into the Essentials repo and loaded automatically
on startup. This will allow for all plugins that use the MC Messengers
library to use the same version without fear of overwriting a dll due to
loading of plugin libraries.
