The old `HTMLRender` is not ideal. 1. It shouldn't be initialized multiple times, it consumes a lot of memory and is slow. 2. It shouldn't depend on short-lived requests, the `WatchLocalChanges` needs a long-running context. 3. It doesn't make sense to use FuncsMap slice. HTMLRender was designed to only work for GItea's specialized 400+ templates, so it's good to make it a global shared instance.
