Since I am striving for closer connection between my task management, my
mail suite and my calendar appointments, it makes sense to unify all
'office' tasks into the single office module instead of keeping
taskwarrior outside of it.
Fixed error in configuration file location for taskopen alias which put
the config file instead of the notes directory.
Now configuration file correctly resides in
$XDG_CONFIG_HOME/task/taskopenrc and notes dir is
$XDG_DATA_HOME/task/notes.
Notes can now correctly be created by doing `task <id> annotate Note`.
