Subject: [PATCH] Add configurable list to ignore files in server watch

The following inside `config.toml` will ignore files ending with `.foo` and `.boo`.

```
watchIgnoreFiles = [ "\\.foo$", "\\.boo$" ]
```

The above is is a list of Reqular Expressions, but note the escaping of the `\` to make TOML happy.

Fixes #1189
