This commit adds support for a new parameter which specifies the type of cache to use for caching. It is specified in config.ini.php: [cache] type = "..." Currently only one type of cache is supported (see /caches). All uses of 'FileCache' were replaced by this configuration option. Note: Caching currently depends on files and folders (due to FileCache). Experience may vary depending on the selected cache type. For now always check if FileCache is working before testing alternative types. References #1000
