This new version of oledump.py brings support for user defined properties and an update to plugin plugin_msg_summary.py

Office documents with VSTO applications have user defined properties. These properties can be extracted with my plugin plugin_medata.py, but not with the current version of olefile.
However, the development version of olefile can be used to extract these properties. This new version of oledump checks if the olefile module has a function to extract user defined properties (get_userdefined_properties), and if it does, it calls it when analyzing metadata:

I added URL extracting to my plugin plugin_msg_summary, a plugin to summarize the content of an .msg file (Outlook email).

This is just a bugfix version.

This new version of oledump.py brings some fixes and an update to plugin plugin_vbaproject to decode and display the password for plaintext passwords:

This new version of oledump.py brings a new plugin (plugin_metadata) and Python 3 fixes for 2 plugins (plugin_msi and plugin_ppt).

The new plugin is actually an old unpublished plugin, that I updated recently.

This plugin parses Office document metadata as defined in document [MS-OLEPS].

I started to write this in 2015 to parse the metadata of Word documents, but soon I figured out that this functionality was already present in olefile, and I introduced option -M to call this functionality.

But recently, I had to parse metadata that isn’t (yet) parsed by olefile, so I updated and released plugin_metadata.
