Title: Added option for maximum level in logLevelFilter

Added the ability to configure what maximum level will match the filter. Now you can filter a range of levels instead of allowing all that are above a threshold.

**Usage**:
Add the `maxLevel` option in `logLevelFilter`, e.g.
```javascript
"appenders": [{
"type": "logLevelFilter",
"level": "DEBUG",
"maxLevel": "INFO",
"appender": {
"type": "file",
"filename": "debug_info.log"
}
}]
```
