Spells: Bard Songs

[Skurd]

A few issues with songs :
- Cinda's Charismatic Carillon (lvl11)
supposed to raise your faction level with your target by 1-2 ranks, currently instantly draws aggo (independently of your faction standing with the target, info); maybe set to offensive instead of friendly or something similar?
- Kelin's Lucid Lullaby (lvl15)
used to be an AE mez in classic, currently only works as single target (info)
- Shauri's Sonorous Clouding (lvl19)
bugs a lot on the initial cast (nothing happens, way way more than other songs, maybe due to the fact it requires a wind instrument to play?), the first two ticks often do not work (displaying "A soft mist surrounds you" and "You become visible" one after the other, maybe the effect of invising is considered an action and breaks invis at first?)
- All songs
->Recurring messages do not display, like for the song above, "A soft mist surrounds you" was displayed every successful tick, it currently doesn't, same for Hymn of Restoration and all kinds of songs that you leave on for several ticks
->No "worn off" messages on songs like Chords of Dissonance(AE DoT) or Largo's Melodic Binding (slow).

I feel like these are issues that are not related to the general timing issues that cause all the other bard song problems and should be able to be solved fairly easily.
