Title: Proposal for an updated mod_rewrite suggestion in the documentation.

Adressing issue #684 as OP mistakes the current suggestion as 'incorrect', the rewrite rules could be changed into this:
```
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
```
This is a flexible solution for new developers in CI and for developers who are unexperienced with the mod_rewrite module.

One of the first questions I found on SO searching for 'codeigniter' and 'mod_rewrite' was this: http://stackoverflow.com/questions/6756181/mod-rewrite-for-codeigniter
I think questions and answers like these suggested supports the documentation suggestion.
