now_playing: text does not roll if it is set to the default 40

[kev-cao]

I noticed that if TMUX_POWERLINE_SEG_NOW_PLAYING_MAX_LEN is left at the default 40, the text will not roll, even if the trim method is set to roll. Dug into the code a bit and found that it was because the relevant AppleScripts first trim the length to 40 — so the text that comes through to the bash script is always limited to 40.

Was there a particular reason why the AppleScripts need to trim the text? If not, I can put up a PR to remove the trim in the AppleScripts and let the bash script handle trimming.

Oh good spot. I see several of the np_*.script trim the length.

I can't think of any reason right now that they should trim. A PR would be great :)
