Options to set cookies

[romanseidl]

Wkhtmltopdf allows for cookies to be set. To set multiple cookes the '--cokies' parameter must be repeated, so the options dict does not work for setting multiple cookies.

I introduced a 'cookies' parameter where you can set a dict of cookies.

Usage example / Test:

import pdfkit

cookies = {'a': 'b', 'b':'c'}
pdfkit.from_url("http://www.html-kit.com/tools/cookietester/", "cookies.pdf", cookies=cookies, configuration=pdfkit.configuration(wkhtmltopdf='./wkhtmltox/bin/wkhtmltopdf'))

This looks great! Can you rebase your fork and fix the merge conflicts? Also some tests?

Cookies shoud now work in master, example from README:

options = {
    'page-size': 'Letter',
    'margin-top': '0.75in',
    'margin-right': '0.75in',
    'margin-bottom': '0.75in',
    'margin-left': '0.75in',
    'encoding': "UTF-8",
    'custom-header': [
        ('Accept-Encoding', 'gzip')
    ],
    'cookie': [
        ('cookie-name1', 'cookie-value1'),
        ('cookie-name2', 'cookie-value2'),
    ],
    'no-outline': None
}

pdfkit.from_url('http://google.com', 'out.pdf', options=options)
