Describe the bug

if the entries in the .vtt file do not start with 00:00.000, which is unfortunately the default behavior, if you use [makesprites.py] and do not manually set the TIMESYNC_ADJUST constant to -1, Indiego-player will not show any thumbs on the cue/progress-bar.

To Reproduce

just manually modify the first entry of a working .vtt-file and increment the start time

Expected behavior

well -- it's in fact a flaw of another application, but nevertheless it would be nice, if indigo-player could tolerate this kind of vtt-files, because the actual cause for this issue rather hard to debug for most users.

[btw: i have to say, your player is IMHO by far the best available open source video player right now! :) ]

...and it also doesn't like additional cue identifiers (as provided by the WebVTT specification)...

* the presence of the 'sips' executable is now autodetected to let it
  work out of the box on non-mac machines

* TIMESYNC_ADJUST isn't neccessary on more recent ffmpeg executables.
  if not set to -1 the time stamps will not start with 0:00.000, which
  is not accepted by some applicationes
  (see: matvp91/indigo-player#56)

* explicit cue identifierers in the output don't make much sense and
  also tend to be incompatible. (e.g. in case of indigo-player)
