Closing tags fix for #228

Fix for #228.

- Rewrite php_closing_tag fixer to use tokens
- Fix closing tags in code with short open tag as well, works only if short_open_tag is enabled
- Extend utests for php_closing_tag fixer
- Add Tokens::findGivenKind method to find given tokens occurrence
- Try to enabled short_open_tag in php.ini
What's the point... yeah, you got the point!
When running from CLI on git project it works fine, but when downloading as phar or downloading by composer and run fron bin project - it has no effects.

I revert that commit.
