Man-page improvements, including the ditchting of docbook2x

[bigsmoke]

The only dependency that is now left for building the man-pages is an XSLT processor. (The Makefile assumes xsltproc.)

I don't quite understand Add missing container el and Document command-line args & cross ref. config stuff. It's the same duplication of sections and stuff we saw before?

My original mistake appears to be that I started working on this branch before the changes from my previous PR were merged into origin/master. (What is now 09cdb09 has been squeezed into 9538541 for origin/master previously.) The same goes for 2febd23.

I removed these two commits from my PR branch and resolved the new conflicts.

Also rebased on your newest master, so that you don't have to resolve the merge conflict on the documentation of your newest config file options.

This is so cool:

I would like to frame it...

Too bad Debian turns the colors off by default, so few people will see it.

There is a slight generation problem in the html version though:

Both literals name flashmq.conf as stray string.

Good catch! I've changed that template to only <xsl:apply-templates select="text()"/>, instead of node(). Previously, the attribute would be caught by node() and processed by the default template, and this only became noticeable with the extra attribute.

By the way: I have not (yet) implemented syntax highlighting for HTML. I'm inclined to use the same (XSLT-based) method, since all the XSLT is bound to this project anyway and I thus see no need for the use of a more general-purpose syntax-highlighting method.

It's merged 👍
