Presets for file patterns

[fvanwijk]

The default patterns for Wallaby are:

config: { pattern: file, instrument: false, load: true, ignore: false }
ignore: { pattern: file, instrument: false, load: false, ignore: true }
lib: { pattern: file, instrument: false, load: true, ignore: false }
mock: { pattern: file, instrument: false, load: false, ignore: false }
specs: { return { pattern: file, instrument: true, load: true, ignore: false }
src: { pattern: file, instrument: true, load: true, ignore: false }

In case you are making a config for Webpack, you want other defaults, ie. load: false. It would be good if there are presets so that you don't need to overwrite the patterns.
