Commit for the 4 aforementioned "features":

Browse Source 
- "Global Pivot": Maintains a global Pivot and Align mode setting for
   all 3d views when enabled, instead of seperate settings per 3d view

 - "Auto Perspective": Switch to ortho mode automatically on 1/3/7, and
   to Perspective when the view is rotated with the mouse

 - "Align mode": As suggested on the list, when enabled, transformations
   on several objects only transform their locations, not their sizes or
   rotations.

 - Grid dotted when not 1:1

***ATTENTION***! The User Interface parts of these features have not been
committed, as I work on my own modified UI here. The three features need
toggle buttons to turn them on and off.

I used the following 3 buttons (first two features are in userprefs,
third as a 3d view setting):

        uiDefButBitS(block, TOG, USER_AUTOPERSP, B_DRAWINFO, "Auto Persp",
            (xpos+edgespace+(3*medprefbut)+(3*midspace)+smallprefbut+2),y3+10,smallprefbut,buth,
            &(U.uiflag), 0, 0, 0, 0,
            "Automatically switch between orthographic and perspective");

        uiDefButBitS(block, TOG, USER_LOCKAROUND, B_DRAWINFO, "Global Pivot",
            (xpos+edgespace+(4*midspace)+(4*medprefbut)),y3+10,smallprefbut,buth,
            &(U.uiflag), 0, 0, 0, 0,
            "Use global pivot setting for all 3d views");

    uiDefIconButS(block, TOG|BIT|10, B_AROUND, ICON_ALIGN,
                xco+=XIC,0,XIC,YIC,
                &G.vd->flag, 0, 0, 0, 0, "Translate only (align)");

Someone needs to add these to the interface in an appropriate manner!

Thanks.
