* Added strong naming for the .NET Framework 4.x dlls as was discussed in #3. Strong naming doesn't help for security but it's sometimes needed as companies want to build strongly named assemblies themselves, and these can only use other strong named assembly. The general way to do this, is to sign the assembly with a public known snk file (Which is in the repository) so it's strongly named but without negative side effects.
* Fixed a tricky issue with .resx files, concerns GenerateResourceUsePreserializedResources and dependencies.
* Fixed the copyright years.
* Fixed an issue with SystemInfo, somehow the DpiFactorX/DpiFactorY weren't initialized.
* As net45 doesn't build with "dotnet build", we need to use msbuild instead.
* Removing unneeded packages for net4x
* msbuild needs nuget restore before the build to work
* Make sure that PRs don't push the packages to the nuget feed (will fail anyway)
* Modified the WindowMessageSink to use an enum where possible.
* I managed to find more of the windows messages, and it was worth it. I expect that there is a bug, while currently two events aren't handled: WM_CONTEXTMENU & NIN_SELECT. Why can be read here: https://docs.microsoft.com/en-us/windows/win32/api/shellapi/nf-shellapi-shell_notifyiconw. Also added NIN_KEYSELECT
* A small stability fix, although it most likely wouldn't happen that the MouseEventReceived isn't assigned it's done so in a different location and might hit us somewhere in the future. I also removed unneeded assignments.
* Applied some code conventions, used more current language features which should improve readability and making it easier to re-factor / modify. Also fixed some typos in documentation.
* Changes based on PR conversation for the SystemInfo
* Some modifications due to conversations on the PR, especially I removed the FlagsAttribute on the BalloonFlags.
* Removed Silverlight targeting in code.
