This adds copyright/license notification blocks CMake's find-modules. Many of the modules had no notices at all. Some had notices referring to the BSD license already. This commit normalizes existing notices and adds missing notices.
These files were committed to the repository with Windows newlines. This converts them to Unix newlines so they will show up natively.
* Improved examples * Switched to FindPackageHandleStandardArgs * Cleaned up indentation * Sanitized else()/endif() blocks
