Cleanup patch 3 - code comments

[Patch date 2003-06-07 11:30]

This changeset consists of three different parts:

HttpDialog.cpp was missing from cleanup.2 sources. Anyone who read the docs and tried to compile probably did the obvious patching themselves, but here it is.

emule.vcproj organization. Namely moved three gifs from main level to resources, and removed resources that were listed under main directory leaving their res-dir counterparts in.

Code comments. Copied over from light some comments regarding which classes/methods use many of the class members. These are always denoted by "Used by:" list immediatelly preceding the member.
