elyxer, Converters, Etc: Problems in Trunk

[rgheck]

There's still a problem, at least in trunk, with the elyxer detection 
code, though the actual bug, I think, is somewhere else.

The problem with the code is that we should NOT be refusing to check for 
LaTeX-->HTML converters simply because we have found a LyX-->HTML 
converter. Once we have the ability to allow the user to choose among 
various options, then we want to know if there is an alternative, even 
if elyxer becomes the default. Indeed, though it's hard to imagine, the 
LaTeX-->HTML converter could possibly be used in some other converter 
chain, i.e., other than LyX-->HTML, e.g.: DocBook-->LaTeX-->HTML. Not 
that I'd recommend it.

It's easy enough to re-instate such detection, but then the problem is 
that elyxer is not used for HTML output. Instead, the LaTeX-->HTML 
converter gets used. This seems wrong, because LyX ought to be using the 
shortest path it can, which would be LyX-->HTML, not LyX-->LaTeX-->HTML.

Does anyone have any idea why the LyX-->HTML converter isn't being found 
first in this case? I really don't want to add a ton of debugging code 
to Graph.cpp to find this out....
