Multiple fixes on the addition of new raw files

The initialize function has been updated with a new possible option for
a new raw file, where the Last Accessed date changed the content hadn't.
Also removes sort() when using extend() on a list as it doesn't work
correctly.
Categorization code moved to if False statement to add posterior toggle
behaviour.
New transaction print added (.desc()) which prints the description of a
transaction instead of its category to help on the manual
categorization.
Raw files now on raw dir instead of .raw
It now also accepts empty lines and # at the start for comments on data
files. TODO these are overwritten whenever the data files are updated.
