Bug 471875 - [IconExe] Improve error message when launcher's icons has not been replaced

Provide more details in error message and show what icons actually has
not been replaced:

    [IconExe] Error - 3 original icon(s) not replaced in /win/eclipse.exe:
        - 48x48, 32 bits, 9640 byte(s) @ 38384
        - 32x32, 32 bits, 4264 byte(s) @ 48024
        - 16x16, 32 bits, 1128 byte(s) @ 52288

We don't know what input files were actually used (we accept one or more
files with icons) thus not reporting input filename in error message.

Also restore documentation about icons used in launcher 3.4 for Windows
by partially reverting commit a2f9d54d4ec55e27d28b6c522a2940b309729f11.

Because the source code is the only source of information about
requirements for icons, show the link to the browsable source code in
error message.
