Title: Removed failing class_exist()

```php
if(class_exists("cssmin"))
```
always returns false, the class actually has various names like `CssMin`, `CSSmin`etc. (look at the case sensitivity).

This case has definitely to be refactored to a more dynamic solution, but at least with this fix it will work with https://github.com/mrclay/minify
