Do not list core mods as tools

[Iritscen]

I thought this had been reported before, or even fixed, but maybe my memory is faulty. Currently, the AEI prints the core mod packages twice at the top of Installation.log:

AEI2 version: .26
Installed tools:
 - OniSplit (AEI) (0.9.95.0)
 - XmlTools (2.0b)
 - XmlToolsDependencies (1.2)
 - AE Read-Me (2015-03)
 - Oni game app (Mac OS X, Intel) (1.2.1) (! LOCALLY MODIFIED !)
 - Menu Fixes (AE) (1.1)
 - Globalization Fixes for Characters (1.2)
 - Custom Character Variants (1.1)
 - Airport Vehicle Fix (1.0)
 - Bomber Fix (1.0)
 - Widescreen Fixes (1.11)
 - Unlock All Moves (1.3)
 - Vanilla BSL (1.1)
 - Missing Sounds (1.0)
Installing mods:
 - Menu Fixes (AE) (1.1)
 - Globalization Fixes for Characters (1.2)
 - Custom Character Variants (1.1)
 - Airport Vehicle Fix (1.0)
 - Bomber Fix (1.0)
 - Widescreen Fixes (1.11)
 - Unlock All Moves (1.3)
 - Vanilla BSL (1.1)
 - Missing Sounds (1.0)
 - Smart Barabas (1.2)

It helps readability if we can remove those core mods from under "Installed tools", but I'd like to suggest going a little further and breaking the installed packages into three groups, "Installed tools", "Core mods", and "Optional [or "Selected"] mods" so that we can quickly see just what the user has selected for installation.
