Translation parser

A PHP helper script to scan a DustPress theme for translatable strings with POedit. Put it in a subdirectory under the root directory of you theme (for example /utils) and run the script which must have writing permission to its directory (thus it is preferable to run the script via command line).

The script then writes a file called strings.php containing all strings defined with {@s} helper in a format that can be scanned with POedit.
