Ability to change portions of the published URLs

[chriss577]

Is your feature request related to a problem? Please describe.
I love Xteve, but I hate that the URL has to be the same across every single global installation.

Describe the solution you'd like
I would love a way to customize some or all of the published URLs. For example, instead of http://127.0.0.1/m3u/xteve.m3u, it would be great to be able to customize the filename, such as http://127.0.0.1/m3u/mytacostand.m3u . A similar functionality for the .xml would be great as well.

Describe alternatives you've considered
I'm not aware of a way to run Xteve and publish different urls.

Additional context
None.
