Improve out-of-box experience (OOBE) for new user's first build

[jspraul]

Some minor tweaks and clean-up to improve a new user's first build.

• Reduce .NET framework to v4.5 in all projects referenced in solutions in source control
• Fix ProjectGuid conflicts (entities solution disagreeing with everything else)
  • Also include missing Components project in entities solution
• Fix NuGet hint paths so that projects build cleanly
• Add a solution to build the SqlParser UI
• Change SqlParser UI to stop processing if parsing fails (avoid NullReferenceException)

I tried to keep the changes minimal and granular enough that you can pick and choose what you want to apply, if anything. Unfortunately the .NET 4.5 change (to reach a slightly wider audience) was done before the hint path change, so there may be a slight conflict if you want the hint path fixed without .NET 4.5.

There is a lot of interest in parsing SQL in C#; you might gain some developers if you document more about how you're doing that!

Any documentation on how to build (still have to build entities solution twice!) and use the project would be a great addition to the README. Thanks for your consideration & keep up the good work!

Hey,

I'm glad you found it useful. I'm currently working on building issues and continuous integration but this is a big and complex project and I'm the only developer right now. I was also considering factoring out the parser project entirely, maybe will do it sometime. I'll take a look at your pull request sometime this week.
