Loop through the iconlist until an icon is found

When the iconlist was smaller then 5 items, it would cause a panic.
Solved by using .truncate() on the iconlist.

Loop for a maximum of 5 times through the iconlist or until a
successful download of an icon.

Fixed issue #380

 - Created a separate function for parsing the sizes attribute
 - Parsing sizes now with regex
 - Should work with any non-digit separator

Added cookies to the icon download request.

Some sites use XSRF Tokens, or other Tokens to verify a subseqense
response. The cookies which are sent during the page request are now
used when downloading the favicon.

A site which uses this is mijn.ing.nl.

Changed the way to fix the href

 - Using url from reqwest to fix href, this fixes:
   + "//domain.com/icon.png"
   + "relative/path/to/icon.png"
   + "/absolute/path/to/icon.png"
 - Removed fix_href function
 - Some variable changes
