Subject: Adding the ability to change "Last Updated" field

This commit adds the ability to change the behavior of the "Last Updated"
field at the bottom of the html documents generated by asciidoc.
This will be done by using the "footer-style" new attribute.
This commit adds the ability to change it to the revision date or to skip it.

This commit also adds the documentation of this new feature to the user guide.

+Changes the "Last updated" field in the footer of the document or removes this

+Can take 3 values:
+
+- none : Don't display the "Last updated" and "Revision number" fields in the
+  footer of the document
+- revdate : The "Last updated" field's date in the footer will be the revision
+  date specified in the document (`revdate` attribute)
+- default (or any other value) : The "Last updated" field's date in the footer
+  will be the date of the input file modification
+
+This attribute can be set, for example, using `:footer-style: revdate` in the
+header of the file or using the `--attribute footer-style=revdate` command-line
+option.
