Allow navbar to stay fixed on page

[Piernas]

Small addition to allow navbar to stay on screen when scrolling the
content of a page.

Perhaps it would be better to reverse the logic so that if added to an existing store without uninstalling and reinstalling, the previous behaviour doesn't change
$navbar_fixed = (MODULE_CONTENT_NAVBAR_FIXED == 'Yes') ? ' navbar-fixed-top' : '';

Thanks

Installer (SQL) change.
CSS change.

Please solve these and push.

[gburton]

Please rework the submission so that shopowner can choose "top", "bottom", "default".
SQL Installer needs updating
CSS needs updating

[Piernas]

Done!

Optimises the code a little bit..

Hi,

For mode: on top

Example: create_account.php on mobile device

When you miss selecting radio button M / F and click on Continue

you will not see the option button M / F, because it is hide by the navbar. You have to scoll up so see it.

Better would be to implement a offset of the high of the navbar. But i do not know how to do.

Also in the Destop mode same issue

By the way ... is it possbile to implement a logo in the navbar? It doesn't look really nice.

Thank you :)
