Added an indicator for when processes haven't been found and notifies the user that they can show all clients if they are not doing so already

Proof of working

For author to do

  Additional info

  I had issues related to signing certificate in the certificate store when I tried running it with the debugger even before I edited any code. I deleted:

  <PropertyGroup>
  <ManifestCertificateThumbprint>F0BB6B4AB81DCB530A46721FAE58938516286746</ManifestCertificateThumbprint>
  </PropertyGroup>
  <PropertyGroup>
  <ManifestKeyFile>BorderlessMinecraft_TemporaryKey.pfx</ManifestKeyFile>
  </PropertyGroup>
  <PropertyGroup>
  <GenerateManifests>true</GenerateManifests>
  </PropertyGroup>
  <PropertyGroup>
  <SignManifests>true</SignManifests>
  </PropertyGroup>

  However, I left it out of this pull request as I believe the error occurred at the fault of myself.
