New plugin/s to looking for metadata information. Wen can use this tools:

• https://code.google.com/p/metagoofil/
• https://pypi.python.org/pypi/hachoir-metadata

We have very rudimentary support for metadata extraction now (using PIL to get the EXIF tags for GPS coordinates).

When we add this plugins also add the rest of data types :)

Yep, that's the idea. Only with the plugin we'll know exactly what information we need in the data types.
