Refactor the accesors to behave like methods instead of properties.
This means all accesors will be prepended with the string
"get_" and will include a set of parenthesis.
Improve the ModeAttribute class to use the method's
short_description. This commit also adds support for a
new method .help_text attribute has been added.
Move accessors to their own module, named "methods.py".
Remove the PropertyHelper class as the accessors no longer
need it.

Add the file metadata app. This app uses binary wrappers called drivers
to extract properties from the file of documents. The default driver
uses the exiftool to extract the EXIF record from JPEG images.
The exiftool can also extra some properties from other files like
PDFs, office files and sound file.
