Honestly, I consider 17 files to be not that much. The current project I 
work on at work has 91 files in the main dir and I don't feel like it's 
a problem.

I agree, however that something must be done for utils.py :)

Most functions are db related, so I would move them to dbutils.py:
addTask
getTaskFromId
getOrCreateKeyword
getOrCreateProject
createMissingKeywords
=> dbutils.py

getProjectFromName
=> projectcmd.py (only used here)

getItemPropertiesStartingWith
=> completers.py (only used here)

exportTasks
=> disappear if t_export is merged with t_list

Only thing remaining is ENCODING. Don't know what to do about this one
