Frontend network control in 0.25 is asymmetric with respect to music jump point

[Gregory Moyer <moyerg@…>]

In 0.24, the jump "playmusic" resulted in a location of "playmusic".

However, in 0.25, the same "playmusic" jump no longer returns the same location response.

playlistview

This makes code for external libraries slightly more complicated. It is also a little less than intuitive for the user typing commands into the network control socket.

The attached patch adds "playlistview" as a synonym to "playmusic" to allow for symmetry between the jump and the resulting location, while not breaking anything or anyone expecting "playmusic" to work.

Synonyms have been created in the past with other jump points (i.e. playbackbox and playbackrecordings), though I do not know the reasoning behind those.

Paul, this looks like a very easy one to close.

networkcontrol: add "playlistview" as a synonym to "playmusic" jump point

This allows for symmetry between the jump and the resulting location, while
not breaking anything or anyone expecting "playmusic" to work.

Fixes #10698.
