Make it easier to build the source under Linux

[moodmosaic]

• Make csproj files shorter
• Make csproj files easier to maintain
• Most important, replace paket.exe with dotnet.exe which means there's no need to install Mono.

Just run dotnet build in the root folder and that's it.

Many thanks to @stjordanis for all the work and tests he's been putting in. 🚀
