Documentation Update.
* Add modelines to all code/doc files excluding README.md.  The modeline used is: `" vim: set expandtab sts=2 ts=2 sw=2 tw=78 norl:`
* Rename links with /vundle to /Vundle.vim, seems to confuse some people with redirect.
* Remove duplicates from Quickstart, add example of name opt.
* Add link to Tips page by @Lucc
* Change help maintain vundle link directly to the new one.
* README.md line number links updated.

Note: We will need to reclone Vundle.vim instead of vundle to continue using the test files. Existing users that don't need to run these can stay on
vundle as long as they want.
