Merge finding-index.md into edit-index.html

It is unnecessary to have this two separate files.  Merge them into
one.  This way all information is delivered with just one click.
Also, the wiki gets even less clutter (there is few, or no, clutter in
~club wiki).

Also make small changes to edit-index.html file.
