SailWave patched with XML import/export

Official builds here: https://openrepos.net/content/ejjoman/sailwave

A proof-of-concept/mvp of an internet radio player with XML import/export, implemented using just qml+js. Import supports both local as well as remote files (and so does export, if the given server allows PUT requests).

Feel free to copy the implementation(s), I made this since there isn't a good radio app with import/export functionality out there. Code available here: https://github.com/Jollailija/harbour-sailwave

Limitations & warnings:

- will install over your existing SailWave

- import formats: only Nettiradio/asemat.xml

- export formats: VLC/xspf and Nettiradio/asemat.xml

- import doesn't validate stations

- the default export path, /home/nemo/ is deprecated

- SailWave doesn't have a way to reset the db, so you must do it by manually deleting the database if you mess up
