Added alias within taskwarrior to invoke taskopen through
(unsurprisingly) `task open`. Importantly, the difference to other
taskwarrior commands is that the number of the task to open should come
AFTER the command, not before as a filter as for all the others. Perhaps
that can be changed in the future.
Updated the formatting of the taskopen configuration file to conform to
its new display.
Updated the xdg-conforming `taskopen` alias to use long-form option
since the short-form option seems bugged at the moment.
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`.
