dzpackageinst SVNCode

updated list of (already) supported Delphi versions in help

* changed externals to point to OSDN (which is the current version of dzlib)
* Normalized .dproj
* renamed variable s to OrigName to better reflect its purpose

Bugfix: TRegistry_ReadString returns the read string as result, not as parameter, so BplOutput was never actually set (how did this ever work)

* added externals
* changed _icon.rc to work with MS resource compiler
