enable to upload files using multipart/form-data
idea from:

u = urllib2.urlopen('http://site.com/path' [, data])
data can be a mapping object or a sequence of two-elements tuples
(like in original urllib2.urlopen())
varname still need to be a string and
value can be string of a file object
eg:
((varname, value),
(varname2, value),
)
or
{ name: value,
name2: value2
}
