[bug] Tv1channel plugin no longer works
## Bug Report
<!-- Replace [ ] with [x] in order to check the box -->
- [x] This is a bug report and I have read the contribution guidelines.

### Reproduction steps / Explicit stream URLs to test

http://tv1channel.org/index.php/livetv fails to open. Stream seems to have moved away to a m3u8 link - either a quick fix or just remove the plugin as it is covered by one of the main plugins.
