Add synctex support

pdflatex has a neat option that adds functionality that is best described with a video:

This is easily done by using -synctex=0 in the first passes and -synctex=1 in the last
one.

Whoa - that's pretty cool.

Sorry for the slow response time, by the way.  This project is always the first to
go when things heat up at work. :-p

So, one problem with this is that we never really know which pass is the last pass.
 Sometimes the first pass is also the last pass, and sometimes it isn't - you just
never know until the logs say "you're done".  Is there any other kind of logic we can
apply to make this work (without adding an additional last pass *every time*)?

The obvious way out is to add it to all latex runs. I don't think it is expensive.
(How can the cost be benchmarked?)

Well, we could look at a very large document and see how much longer it takes with synctex
versus without.

I'll happily look at a patch for this.  You'll want to change the commandline options
in the run-latex function to include synctex=whatever, and then you can test it and
see if it works properly.  :-)
