Support of different attribute selectors

[PavelFil]

I would be useful to support next kinds of attribute selectors:

[attribute~="value"]
[attribute|="value"]
[attribute^="value"]
[attribute$="value"]
[attribute*="value"]

I am really surprised these doesn't work in hQuery.
@duzun Dumitru, do you still use your library?

I still use this lib in some old and still running projects, but I'm not actively investing time in it.
PRs are welcome!
