Add next/previous page buttons to internet radio search

[SteveMicroNova]

curl -X POST https://de2.api.radio-browser.info/json/stations/search -H "Content-Type: application/json" -d '{
    "offset": 0,
    "limit": 10,
    "name": "soma",
    "hidebroken": "true",
    "order": "clickcount",
    "reverse": "true"
}'

This request allows you to filter how many stations you request from the server. This one filters for the ten most popular stations with "soma" in their data, if you set offset to 10 it would be the ones rated 11-20 and so on

Add buttons that increment the offset to help with internet radio browsing
