Respect cjklib.conf url setting when installing dictionaries

[cburgmer]

See #1.

We want to configure where dictionaries are stored to.

@cburgmer : In the other ticket we mentioned this may require another solutions / perhaps a small refactoring. Any chance you'll be able to take a stab at it in the near future?

Perhaps a quick high level overview of what objects/contexts are passed around in cjklib? Even parts that aren't elegant and need change should be put into perspective imo. Then we'll have piece of mind refactoring/patches don't break any inner workings that weren't understood at first.

To chime in on this - I'm getting more familiar with the library and delving more into it. I'm really greatful for the work and others put into it. It's a jewel 👍
