Support alternative date formats when inputting

[ghost]

First of all, thanks a lot for this project. I like it a lot so far, except for one thing. I am Dutch, and here we use either yyyy-mm-dd or dd-mm-yyyy, but never mm/dd/yyyy and as such this format can be confusing for me (and most people outside the US). This is no problem for the output which can also be configured, but when inputting entries the following both do not seem to work as expected:

jrnl 1-12-1990 at 12:00: a long time ago => 2014-06-25 12:00 a long time ago
jrnl 1990/12/1 at 12:00: a long time ago => 2014-06-25 12:00 a long time ago

Hi, that's a very valid point. This has already been on my mind from the very start (see #10) but I never quite got around to it. I'll work on it for the next major release though!

This was apparently closed via maebert@49f67df in 2014, yet I can't find any documentation on how would I change the language format to something other than English. Is the functionality implemented but not documented (or have I missed the relevant part?) or is there still some part left to be implemented.

UPDATE

Just looked at jrnl_config. There we can set timeformat which helps.
But words like yesterday and 2pm etc. remain special. It would be neat to be able to parse lines like: jrnl 14:00: something instead of jrnl 2pm: something
or eg (in German): gestern: something.
