Feat: Add support for automatic scans.

I must admit - this escalated a bit ;)

I just wanted to add support for automatic scans so that Vale CLI does not always need to be triggered.

Somewhere on the way I discovered that vale can apply fixes directly and implemented that aswell.

There is also wildcard support for file extensions - I am just dipping my toes in the water with vale but the way I see it, it makes sense to have the vale.ini-configuration only target the files you need to check so a simple '*' in the extension might actually work best in many instances.
