Change MeshRdpFile.rdp to be the Device Name File.rdp with Mesh Central Router

Thank you for all your work on Mesh Central it is an awsome tool.

As I've been using the RDP link via Mesh router, I find that I have multiple windows starting with "MeshRdpFile - 127.0.0.1:" and I can start to see where keeping track of which RDP window is which machine starts getting confusing.

Since mstsc.exe appears to put the RDP filename in the title first, I thought that a possibly simple change would be to use "Device Name File.RDP" instead of "MeshRdpFile.rdp" as the File Name when launching a RDP File with Mesh Central Router would improve the experience.
