This commit implements the .tex-based online help system in LON-CAPA. It
may be necessary to manually run loncom/build/help_graphics_converter.pl
and doc/help/rebuildLabelHash.pl after a cvs update, and
loncapa_apache.conf may need to be manually copied to /etc. (The
loncapafiles.lpml has been updated.)

After merging this, the URL http://[loncapahost]/adm/help/Foils.hlp
should display a help file.

Also, some *very* out-of-date files have been removed from the /doc
directory.

"""simpleEdit can be used to edit the tex fragments in context
determined by a texxml file.

Use:

python simpleEdit.py [name of texxml file]

simpleEdit will read the texxml file, and present the referenced tex
fragments in order determined by the file. When you save (CTRL-S),
simpleEdit will save all the tex fragments back to their little
files.

Very, very simple.
