Could not add extra lookup sources

[Vaughn Li]

hi, I could not add another lookup sources. e.g: DuckDuckGo https://duckduckgo.com/{word}
More details here:

Since Google dictionary triggers its annoying CAPTCHA, hope more sources could be added.
Thank you in advance.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
