v0.3.2

What's Changed

• Add canfigger_cache_dir(): $XDG_CACHE_HOME/appname or $HOME/.cache/appname
  on POSIX; %LOCALAPPDATA%\appname on Windows
• Add canfigger_config_file(): returns $XDG_CONFIG_HOME/filename or
  $HOME/.config/filename, for config files that live directly under the
  config root rather than in a per-application subdirectory

• Headers are now installed to /usr/include/canfigger/; the pkgconfig
  Cflags is updated accordingly so #include <canfigger.h> continues to
  work without changes
• Only build examples if not a subproject
