[TYPO3-core] RFC #14935: Install tool password can be overwritten by an extensions' ext_localconf.php

[Benjamin Mack]

Hey,

this is a SVN patch request.

Branch: trunk only

Type: security feature

Bt reference: http://bugs.typo3.org/view.php?id=14935

Problem:
The Install Tool Password can be changed by any extension that is
installed. It should only be changeable in localconf.php

Solution:
Use a constant instead of the variable - throughout the Core.

All the best,
benni.
