CSS Crush

A pre-processor is a tool for interpreting CSS before sending out to the client.

This means that the developer can add CSS in a more complex syntax, and then send it to the pre-processor to convert it into standard CSS code.

What is new in this release:

• Rule nesting now works without `@in` directives.
• Added `csscrush_add_function()` as a simple way of adding custom functions without plugins.
• Added alternative directive names: `@set`/`@ifset` for `@define`/`@ifdefine` and `@selector` for `@selector-alias`.
• Added support for a command line config file (`crushfile.php`).
• Added `Util::readConfigFile()` method to enable easier configuration sharing between different workflows; esp. command-line and server.
• Protocoled `@import` directives are now hoisted to the top of output.
• Default output filename now uses `.crush.css` suffix only when outputting to the same directory as input. Otherwise a regular `.css` suffix is used.
• Updated vendor aliases.
• Removed math shorthand syntax.
• Deprecated `@in` directives. Supported until at-least 3.x.
• Deprecated `@define`/`@ifdefine`/`@selector-alias` in favour of new directive names. Supported until at-least 3.x.
• Deprecated the static api methods in favour of the `csscrush_*` functions. Supported until at-least 3.x.
