Add default value to get command

[dotKuro]

I set the default for the get command to "state:open" as stated in #18

Just ignore the last two commits. The first one should be pushed to another branch and the second one just reverts the first one. 🙈

That won't work. Filter expressions are anded, so it's not possible to overwrite it the way you implemented it. tl get state:open AND state:done makes not sense.
It must be implemented somewhere in the runFilter function or similar

[dotKuro]

No tl get state:done works perfectly using this method.

The parser looks for at least one string argument other whise it will fail. The <|> provides an alternaitve in case the parser fails. Which means it will either use any arguemnt provided (i.e tl get state:done) or when no arguemnt is provided (tl get) it will use state:open instead.

Is that what was meant with the todo? I might got it wrong.

Ah ok, sorry, didn't properly read the code.

But this means that tl get would list all open tasks like tl open.
I think I'd prefer that it shows the help text if the filter expressions is misssing:

$ tl get
Missing: FILTER_EXP

Usage: tasklite get FILTER_EXP
  Get all tasks filtered by the specified expressions by priority

[dotKuro]

This is exactly the behaviour upstream has currently.

I propably missunderstood the todo.

(40gs) Use state:open per default for the tl get command

What was this suppose to mean? If you not specify state: after get it should always implicitly use state:open?

[ad-si]

If a filter without a state expression is specified
then add expression state:open
else (there is no filter) show help message

Thanks a lot for the PR!
