Generate HTML via make4ht

So the patch basically add some script for generating html files.

In html.cfg :
Add tables of contents
Specify the layout of lkmpg.html

In Makefile :
Add a new target `html` for generating html files and put them in html/
directory.
Add a symbolic link `index.html` linked to `lkmpg.html`

In lkmpg.tex :
Turn off the \tableofcontens section when using make4ht to prevent
from errors
