Bjørn Erik Pedersen 9cd54cab20 Move the emoji parsing to pageparser 
This avoids double parsing the page content when `enableEmoji=true`.

This commit also adds some general improvements to the parser, making it in general much faster:

```bash

```

Running some site benchmarks with Emoji support turned on:
