Add language to the received parameters

Add debpaste.el client

Less strict check of Content-Type

A string "text/xml; charset=utf-8" can pass the check now.

Allow for only remembering the name

Add a checkbox to remember the paster's name only.

Add github URL to about template

Add link to https://github.com/formorer/paste.pl to templates/about so
possible contributors know where to put their pull requests. :)

Make text belonging to a form element a label

Put <label for="...">...</label>¹ around the labels describing a form
element so users may click on it to toggle a checkbox or jump to a
textarea or so.
