Add the baseline of the JSON performance runner.

This commit creates the baseline. It introduces terms like subject,
case and procedure. It implements most probable scenarios and uses
the most popular JSON frameworks. It prints all collected results
to the console.
Refactor reporting and PlainTextPrinter.

The patch adds ISubjectInfo and ICaseInfo to reporting in order
to get information about fulfilled requirements. The plan reporting
class is refactored to small methods.
Add README.md with current benchmark results.
Introduce new subject: fastJson.

This subject supports all cases but requires a little adjustments
for support case-insensitive scenarios.
Support console line build system.

The patch introduce restoring packages, building and executing
benchmarks directly from the console line using PowerShell. In
order to build projects the Invoke-MsBuild PowerShell module is
used.
