Theme editor does not look in subdirectories of child themes or for CSS files

[janfabry]

#4131 added support for files in subdirectories of the main theme directory. However, it seems this code was only added to the code branch that looks for PHP files in the main theme, not to the branch that scans child themes and CSS files.

This means that:

• main-theme/
  • subdir/
    • myfile.php will be found
    • myfile.css will not be found
• child-theme/
  • subdir/
    • myfile.php will not be found
    • myfile.css will not be found

Maybe the subdirectory scanner should be made recursive, so files in main-theme/includes/great-library/ can also be found.
