Title: Update installation/model/languages.php

Replaced hard-coded use of extension id 600 by a query for the en-Gb language pack and added $db->quoteName wherever it was missing.

This is the last place where the hard-coded extension id 600 is used. With this PR we get rid of this.

The change for this is similar as done for the com_installer with PR #5327 .

**Testing:**

There should be no change, all should work as before ;-)

Details:

Perform a new installation of a a Joomla package (3.4.0-dev or alpha) with the patched file from here in the installation/model folder.

A the (normally final) step after the installation has finished, do NOT press the button to delete the installation folder.

Instead of this, chose the optional step for installing additional languages (button on the right hand side) and go through the language installation, i.e. install some additional language and adjust some of the languages-related setting in the following step.

Then at the end, delete the installation folder on the last page and login to the admin interface.

Verify that additional languages have been installed and changed lhave been applied.

If all this works as it does without this PR, then all is fine.
