Feature: #81223 - includeCSS.inline property 

See forge#81223

Description 

A property .inline has been added to page.includeCSS . If .inline is set, the content of the css-file is inlined using <style>-tags.

Impact 

Example:

page.includeCSS {
   inline = EXT:test/Resources/Public/Css/inline.css
   inline {
      inline = 1
      forceOnTop = 1
      media = all
   }
   other = EXT:test/Resources/Public/Css/other.css
}
Copied!

Some notes on the implementation:

External files are not inlined. The inline-css is compressed if config.compressCss is set. Most other properties ( .allWrap , .disableCompression , .forceOnTop , .if , .media , .title ) work even if .inline is set. If .import and .inline are both set , the file is loaded via @import.
