Flash support for ZeroClipboard is not working in project pages since
the SWF file is missing. There was a typo in the .gitignore file that
ignored "*.sw?" files.
Remove the use if "unless contains 'not found in _includes directory'"
hacks that were previously used to detect when _includes were missing.
This change is required as the hack no longer works with the latest
Jekyll release (and therefore also with GitHub).
Additional 'custom_pom_template' and 'custom_gradle_template' flags
must now be set in _config.yml if you want to include a custom pom.xml
or build.gradle file.
