Create console project to mimic UI

[MetanoKid]

In order to support integration on build servers, it would be nice to have a new project that takes build configuration from command line and outputs the trace file.

It needs, at the bare minimum:

• Path to solution to build: i.e. C:\path\to\solution.sln.
• Configuration: i.e. Debug.
• Platform: i.e. x64.
• Target: i.e. Rebuild.
• Output trace file: i.e. C:\path\to\trace.json.

Ideas for execution with different formats (second one resembles MSBuild a bit more):
builder_console.exe C:\path\to\solution.sln -o C:\path\to\trace.json -c Debug -p x64 -t Rebuild
builder_console.exe C:\path\to\solution.sln /o:C:\path\to\trace.json /c:Debug /p:x64 /t:Rebuild

It would also be interesting to be able to provide:

• Use /Bt+ flag.
• Use /time+ flag.
• Keep intermediate Events.json file.
