v0.15.0

• enhancement: setting the new option Exit code test name results in an additional test per test executable that passes if the executable's exit code is 0, and fails otherwise. Additionally, GTA parses the test executable's output for certain tokens which allow to influence the test's outcome and message. One interesting use case for this is memory leak detection; a complete, reusable example is provided as part of GTA's SampleTests solution (#266, thanks to alfredskpoon for report, example code, and testing)
• enhancement: the GTA extension is now loaded asynchronically by Visual Studio; the drawback is that support for Visual Studio 2012 had to be dropped (#243)
• enhancement: the Show release notes option has been removed, and this release notes dialog has been slightly changed and now has very funny buttons (#270)
• maintenance: reduced code duplication of streaming and batch output parsers (#263)
• donations: thanks, John and Jean-Michel - I appreciate it!
