There are some includes in taskwarrior which make the program error out
if they don't exist on start. This little hook ensures that they get
created each time a new environment is created.
Timewarrior now looks for its data directory in `XDG_CONFIG_HOME`
instead of the home directory. This is a little better than nothing, but
does not separate the configuration and data files from each other yet.
Data *should* be lying in `XDG_DATA_HOME` but the data directory can not
be separated since it relies on a single env var `TIMEWARRIORDB`.
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`.
