Static buttons and automatic requests for lookup callsign data from national callbook web-sites

[R1BLH]

It would bee good to have possibility lookup callsign data from national callbook web-sites like it done for qrz.com and hamqth.com.
It would be good that list of usable source data for lookup be configurable (like bands).

Now after every update from git i add lines for static buttons and menu for lookup in the national callbook (qrz.ru) manually into:
application/views/search/search_result_ajax.php
application/views/view_log/qso.php
application/views/view_log/partial/log_ajax.php
application/views/qso/index.php
assets/js/sections/qso.js

Result looks like:

Agreed nice to have but i feel these need to be user optional else it could get busy quickly

Yes! It would be optional!
