v1.1.1

* Added `Util::unwrap()` which simply unwraps the passed string from the passed delimiter.
* Added `Util::clean()` to combine and clean malformed arrays formed from a parsed expressions.
* `Util::toString()` now accepts a second parameter `$single` for working with flattened or malformed arrays.
* Fix passing an array as the third parameter to `@image`
