USB Apache: change PHP versions and server settings

Open USB Apache settings to select an installed PHP version. In the PHP versions section you can download supported official Windows x64 Thread Safe builds. Installing another version needs Internet access; installed versions remain on your USB drive and work offline.

1. Stop Apache before changing the selected runtime.
2. Open the PHP versions section, choose a supported release and let its download and SHA-256 verification finish.
3. Select the installed version in PHP settings, save and start Apache again.
4. Use the server and PHP settings to adjust port, memory, upload limit, execution time, timezone and extensions.

Keeping extra versions

Additional runtimes are stored in runtime/php-versions. Preserve that folder when moving or updating. Do not delete a PHP version that is currently selected.
