Request: Seekbar Improvements

[Cananbolt]

Option to identify specific chapters easier. For example using colors to identify where they are in the seekbar.

For example, a chapter titled Opening/OP or Ending/ED and so on can have a different colors in the seekbar to identify where it is in the video easier.

For videos that use cache, in the seekbar identify what sections are cached and what sections are uncached. And when hovering over the seekbar it tells the cache range and the remaining seconds till it buffers. As well the part of a video that are uncached.

I guess it'd be possible to what you want for english chapters with those names. However you'd have to refactor the code right now since it currently gets a list of timestamps first, then draws the list of chapter markers/ticks/nibbles. To add if/else logic on the chapters[n].title you'd have to combine those for loops.

The cache already displays the ranges as dark rectangle overlays, and the cache time is in the right side of the controls like the default theme.

Thank you for explaining about the cache. I was not aware of it. I changed the seekbarCacheAlpha = 80 so I could see it better.
