[PATCH] Windows installer: add an "Add/Remove Programs" entry

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

The NSIS script on installation will write a key to the registry
that will be shown to the user as a "Subsurface" entry (with icon)
in the list of installed programs that can be uninstalled
(e.g. in the Control Panel).
On uninstall, said registry key will be removed.

functionality not tested with the patch target file, but with an
isolated test case. should work as expected.
