query-tool: support more field types

Browse Source 
Add options to format the output for the terminal, or IRC messages.

Changed the output format to separate dictionary name with a tab,
so it's now rather similar to tabfiles.

* So far only the `m' field is supported. Feel free to extend the program
* according to your needs, it's not very complicated.
* So far only the `m', `g`, and `x` fields are supported, as in sdtui.
