[Suggestions Needed] Additional CSS Selectors for extracting embed properties

[novacrazy]

Custom sites in the config file now support extracting some embed properties from CSS selectors, such as this for extracting the alt-text on XKCD pages:

[sites.xkcd]
color = 0x96A8C8
domains = ["xkcd.com"]

[sites.xkcd.fields]
image_alt = "div#comic > img < title"

where the < title syntax specifies to extract from the title attribute on the img node.

Full list of available selector fields is Here.

Suggestions for more sites with consistent html structure are encouraged! Note that these fields take the lowest precedence, so any OEmbed or meta tags will not (currently) be overridden.
