Bilibili extractor modification

I'm not sure if it's suitable to open an issue here. when downloading videos from bilibili.com, if the link contains a series of viedos, youtube-dl can only extract the first videos.

for example, download the page on https://www.bilibili.com/video/av28557586/?p=20, it contains a series of 38 videos distinguished by query parameter ?p=xx,

here, I modify code of bilibili extrator, now it works with query string.

here's the patch bilibili extrator

this patch can work on links like https://www.bilibili.com/video/av28557586/?p=20 only.

to download one viedo use parameter %(playlist_index)s like:
youtube-dl -o "%(title)s_%(playlist_index)s.%(ext)s" -f "best" https://www.bilibili.com/video/av28557586/?p=20
