- fix the cloudflare challenge result if the last decimal places
are zero (JS`s toFixed() removes trailing zeroes)
- fix downloading of kissmanga chapter-pages hosted on blogspot
(accessing blogspot with "kissmanga.com" as referrer yields a 401)
- disable certificate validation for 'mangahere' tests
- update flickr test result
Cloudflare challenges, at least for kissmanga and readcomiconline,
now use slightly different Javascript expressions.
Instead of a single value per expression, they now have a numerator
and a denominator of a fractional value, which in the end gets
truncated to 10 decimal places.
