Add customizable subfolder paths with placeholder support

[cegekaJG]

This PR adds the property "FolderPathPattern" to the extension's settings and expands the functionality of the "Reorganize" function. The new property allows users to define a custom subfolder path using the same placeholders used for object and file names. It also adds some new placeholders such as <AlSubFolder> to ensure the default value retains the same behavior as before. Finally, it reorganizes the pattern matching code to remove some duplicate code by reusing functions.
