Issue #207.
Add EditorConfig config.

Fixes #195.
Fix whitespace.
Install SDL2.dll in Win32 Release build.
Use logger.
Trigger console intro text on first console open.

Now that SysConsole is hooked up to the logger, the console intro text
was getting written first, then drowned out by normal log entries.  We
now wait until the console is first made visible before adding the intro
text.
Display the console intro in a different color.
Log each line separately instead of all at once.
Add --no-accel command-line option.

Closes #208.
