Possible Module installer/upgrader [for mod developers]

[yellow1912]

Here is the idea:
Mods should be automatically installed and upgraded if possible.

The current version of this mod takes care of the database part only.

Brief intro:

What it can do:
1. Automatically install new module database patches
2. Execute all database patches in order, so that it will work even if the users skipped several versions.

How it works:

1. All your sql patches should be put inside:
admin/includes/module_installation/your_mod/db/
naming from 0.sql to n.sql

2. For each new version, you will need to pack a specific file called current_version.txt placed in admin/includes/module_installation/your_mod/

module_installer will check compare the patch level it found in database against the current patch level, and will execute all new sql patches in order.



This mod contains 2 classes:
sqlPatch class:
https://svn.rubikintegration.com/zen...atch_class.php

--> This class simply uses all the functions found in ZenCart admin/sqlpatch.php, packed into a class with minor changes.

module_installer class:
https://svn.rubikintegration.com/zen..._installer.php

--> The core of this installer

Comments, code suggestions are all welcome.
It'd be great if we can develop this mod to improve its functionality to make life easier for both developers and users.
