[PowerRename] Regex variables for parent directories

[cow1337killer3]

Description of the new feature / enhancement

Let us retrieve and use the names of parent directories when renaming with PowerRename.

Current item: 'C:\Users\Bob\Downloads\Cool Band\New album\Track 1.mp3'
$p expands to 'Track 1.mp3' (with extension)
$p0 expands to '.mp3' (only extension)
$p1 expands to 'Track 1' (without extension)
$p2 expands to 'New album'
$p3 expands to 'Cool Band'

And it completely avoids the problem of them attempting to include path separators in the new name.

So, renaming from
'.*'
to
'$p3 - $p1 ($p2).$p0'
would give
'Cool Band - Track 1 (New album).mp3'

Scenario when this would be used?

In many cases, files are meaningfully organized by their directory structure, and the parent directories can contain valuable information relating to the file that would be extremely useful when renaming the file. A notable example is music libraries where people often organize their audio files with important metadata information (artist/album/genre) being inferred from the directory structure.
