pgInstaller 8.1 dev build

I've uploaded an initial test build of pgInstaller based on a post-beta
1 CVS snapshot of PostgreSQL. Major changes since 8.1 include:

- Don't install any DLLs into %SYSTEM32%. This means that individual
components can no longer be relocated, but also that there should be no
DLL conflicts with other products or PostgreSQL 8.0.

- Install all development headers.

- Update all bundled drivers and software to latest snapshots, and
update installer as appropriate.

- Don't install Npgsql into the GAC now there is/was/will be .NET 1.1
and 2.0 versions.

- Add a Command Prompt shortcut to open a cmd.exe window in the bin dir.

- Add a Russian translation from Andrey Repko

- Don't ship HTML versions of the PostgreSQL docs - add a shortcut to
directly open the copy of the PostgreSQL docs in the pgAdmin helpfile
instead.

Known bugs/TODOs:

- The Russian version of 'Russian' displays as ?????? On the language
selection dialogue.

- PostGIS requires pl/pgsql, but this is not currently checked or
enforced.

- Service user account creation should be deferred until install time to
prevent problems if the user hits the Back button partway through the
installation.

Feedback is welcome of course.
