New modifier for file properties

[TheGhost78]

Similar to the current # modifier that returns only numerals:

<(System.Audio.EncodingBitrate)> - returns 128 kbps
<(#System.Audio.EncodingBitrate)> - returns 128

Could we have a modifier that returns only the first letter? E.g.

<(System.ItemTypeText)> - returns MP4 (for example)
<(@System.ItemTypeText)> - would return M

We were thinking that to provide full customization JavaScript functions should be supported e.g. <(js:func(System.ItemTypeText))> where func is a JavaScript function.

Yes, that'd be great!
