Add hassil-like template support for configured aliases

Now we have a local voice-powered assistant and that’s great. My native language is Polish and words in my speech can be transformed into a really wild number of forms


so I (and other Polish language users) will be glad if it will be possible to use hassil-like templates to define entity aliases.

tl;dr: I would like to set an alias like Lamp(ę nocną|ka nocna|kę nocną|ki nocnej) instead of having to set 4 different aliases.
