Improvements to YCM dynamic flags.
- Fallback to a "companion" item (e.g. header/source) or a nearby item
when no flags are found for an item.
- Finding a "companion" is also exposed as a standalone script.
- Ability to pass extra clang flags, including some from a special
file found in the .vimcrosoft directory.
- Add support for PCH and other forced-include files.
- Add options for short/long args, or forcing forward slashes.
- Debugging/troubleshooting options, including dumping a batch file and
response file to run clang directly, and the ability to auto-load a
solution's last known environment when running in command line.
