Raise playlist title length limit

[markspolakovs]

Playlist titles are limited to 15 characters by virtue of:

MyRadio/schema/base.sql

Line 292 in 7cbb233

playlistid character varying(15) NOT NULL,

We should consider raising this.

While also remembering to investigate why the limitation was there in the first place. Probably BAPS? (The old one that's rapidly falling out of memory)

@LordAro that does ring a bell - though now that we've fully moved over to BAPS3 it's less of an issue (worst comes to worst we may need to add some trimming logic to some database triggers).
