blowdryerInline

After using blowdryer for a bit, it's made our build files *much* easier to read, since all of our common patterns have been refactored into one repository and it's only the high-entropy stuff that's left to view. My biggest worry is that *other* people will have a hard time reading them, since they are now obfuscated a bit.

Here is a proposed enhancement. It's fine to implement only for groovy or only for kotlin - people who want the other would benefit hugely from the existing as a guide.

## Viewing a blowdryer-enhanced project

If you are working with a project that uses blowdryer, especially *someone else's* project, it can be confusing to track down the build scripts they are calling out to. To address this, you can use `gradlew blowdryerInline` and it will do the following:

- for every gradle file (`foo.gradle`) which uses `blowdryer.file()`
- write out a new temp gradle file (`foo.blowdryer-inline.gradle`)
- where each call to `blowdryer.file()` has been recursively copy-pasted into the expanded file for easy viewing

You can limit this to just one file with `gradlew blowdryerInline --file someFile.gradle`
