Bugfix for checked mode

This is a very minor release, it just patches up name collision errors with a few macros when CHECKS is defined. The reason that we've got a whole new release is because we're now shipping a new benchmark Configuration, which looks a whole lot cooler, and takes around 1.8 times more time to run for the same number of frames as the previous release.

The Benchmark Configuration.txt included in the release archive corresponds to Zoom Video Demo Configuration 3.txt in the source tree of the reimplementation branch.

The SDK target is Windows 10 version 10586 (version 1511, the November Update), so it might not run on older systems.

This program may fail to run without the Microsoft Visual C++ 2017 Redistributables (x64 version) installed on the target system, so in case it fails to run, please install it.

The Benchmark Configuration.txt bundled in the release archive corresponds to Zoom Video Demo Configuration 2.txt in the source tree.

I'll just show the instructions to run the program here (we're just offering the Windows build right now, sorry!):

1. Unzip the release archive such that all items in the archive are in the same directory .
2. Open a command prompt in the directory where the release archive was unzipped.
3. Type ./Mandel.exe "./Benchmark Configuration.txt" (keep the quotes!) and press Enter or Return (if using Command Prompt on Windows, replace the forward slashes with backslashes - you don't need to do this if using PowerShell).
4. The image<n>.tga files should be in the current directory after execution - timing info will be printed out on stdout on console.
